Download or read book A Software defined Radio Based on the Unified SMSE Framework written by Robert James Graessle and published by . This book was released on 2010 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research was to implement a software-defined radio based on a recently developed framework for constructing various spectrally-modulated, spectrally-encoded (SMSE) signals. Two candidate waveforms (MC-CDMA and TDCS) are selected to demonstrate the capabilities of the framework, and they are modulated using antipodal signaling. A transmitter and receiver are each implemented on separate digital signal processor starting kits (DSK). A channel simulator consisting of additive white Gaussian noise and narrowband BPSK interferers is implemented on an FPGA. Burst transmissions from transmitter to receiver through the channel simulator are conducted to evaluate the bit-error rate performance of the system. Results from floating point simulation, fixed point simulation and hardware implementation are presented. The bit-error results from the hardware implementation closely match theoretical results. Also, TDCS is shown to mitigate effects of narrowband interference compared to MC-CDMA.

Download or read book Software Defined Radio written by Walter H.W. Tuttlebee and published by Wiley. This book was released on 2002-06-13 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Software defined radio (SDR) is one of the most important topics of research, and indeed development, in the area of mobile and personal communications. SDR is viewed as an enabler of global roaming and as a unique platform for the rapid introduction of new services into existing live networks. It therefore promises mobile communication networks a major increase in flexibility and capability. SDR brings together two key technologies of the last decade - digital radio and downloadable software. It encompasses not only reconfiguration of the air interface parameters of handset and basestation products but also the whole mobile network, to facilitate the dynamic introduction of new functionality and mass-customised applications to the user's terminal, post-purchase. This edited book, contributed by internationally respected researchers and industry practitioners, describes the current technological status of radio frequency design, data conversion, reconfigurable signal processing hardware, and software issues at all levels of the protocol stack and network. The book provides a holistic treatment of SDR addressing the full breadth of relevant technologies - radio frequency design, signal processing and software - at all levels. As such it provides a solid grounding for a new generation of wireless engineers for whom radio design in future will assume dynamic flexibility as a given. In particular it explores * The unique demands of SDR upon the RF subsystem and their implications for front end design methodologies * The recent concepts of the 'digital front end' and 'parametrization' * The role and key influence of data conversion technologies and devices within software radio, essential to robust product design * The evolution of signal processing technologies, describing new architectural approaches * Requirements and options for software download * Advances in 'soft' protocols and 'on-the-fly' software reconfiguration * Management of terminal reconfiguration and its network implications * The concepts of the waveform description language The book also includes coverage of * Potential breakthrough technologies, such as superconducting RSFQ technology and the possible future role of MEMS in RF circuitry * Competing approaches, eg all-software radios implemented on commodity computing vs advanced processing architectures that dynamically optimise their configuration to match the algorithm requirements at a point in time The book opens with an introductory chapter by Stephen Blust, Chair of the ITU-R WP8F Committee and Chair of the SDR Forum presenting a framework for SDR, in terms of definitions, evolutionary perspectives, introductory timescales and regulation. Suitable for today's engineers, technical staff and researchers within the wireless industry, the book will also appeal to marketing and commercial managers who need to understand the basics and potential of the technology for future product development. Its balance of industrial and academic contributors also makes it suitable as a text for graduate and post-graduate courses aiming to prepare the next generation of wireless engineers.

Download or read book The Demonstration of SMSE Based Cognitive Radio in Mobile Environment Via Software Defined Radio written by Ruolin Zhou and published by . This book was released on 2012 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the emergence of increasing number of wireless devices and demands for higher data rates, spectrum crowding and congestion increases. Spectrum congestion problem has been challenging wireless communication engineers for a few decades. However, recent studies indicate that most of the time wide ranges of the radio spectrum are rarely utilized. Hence, the spectrum congestion is mainly due to the inefficient spectrum usage rather than the spectrum scarcity. To exploit under used spectrum and utilize the spectrum efficiently in dynamically changing environments, a new technology is needed. Cognitive Radio (CR) arises to be a possible solution to spectral crowding problem by introducing the opportunistic usage of frequency bands that are not heavily occupied by licensed users. In this dissertation, we implement and demonstrate an autonomous cognitive radio system in mobile environment via SDR. We first design and implement an intelligent spectrum sensing engine which can detect the existence of the primary user (PU) signal and accurately estimate its radio frequency (RF) parameters. Second, with the aid of the spectrum sensing engine, a spectrum mask is provided. Meanwhile, a multi-carrier waveform is generated based on spectrally modulated spectrally encoded (SMSE) framework. With the dynamic multi-carrier non-contiguous waveform, an intelligent interference avoidance SMSE-based cognitive radio is implemented and demonstrated using universal software radio peripheral(USRP) and GNU software defined radio (SDR) platform. Third, we propose a novel total intercarrier interference (ICI) cancellation scheme to eliminate the ICI in mobile environment, apply the algorithm to the SMSE base cognitive radio, employ GNU SDR platform and USRP, implement and demonstrate an SMSE based cognitive radio in high mobility environment. Combined with the spectrum sensing engine, the cognitive radio is capable of detecting the availability of each and every subcarrier in the operational bandwidth. By turning off those subcarriers occupied by the primary users, the cognitive radio implements a non-contiguous SMSE transmission waveform. Integrated with total ICI cancellation algorithm, the cognitive radio has the ability to eliminate the ICI due to the frequency offset caused by mobility. There are a few unique features of our cognitive radio implementation: (1) we have demonstrated real-time seamless video transmission without interference to primary users, and without interference from primary users; (2) our cognitive radio is capable of taking advantage of multiple spectrum holes and operating over multiple non-contiguous spectrum bands (our demonstration is the first in the world to stitch multiple non-contiguous spectrum holes together); (3) the cognitive radio dynamically adjusts which subcarriers to turn off according to the primary users'transmission; (4) the cognitive radio can also adjust other parameters such as the total number of subcarriers, center frequency, and bandwidth of each subcarrier; (5) the cognitive radio maintains all the features even in high mobility environment, making it a flexible, agile, and robust cognitive radio node in mobile communication system.

Download or read book Software Defined Radio written by Markus Dillinger and published by John Wiley & Sons. This book was released on 2003 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Software defined radio (SDR) is a hot topic in the telecommunications field, with regard to wireless technology. It is one of the most important topics of research in the area of mobile and personal communications. SDR is viewed as the enabler of global roaming and a platform for the introduction of new technologies and services into existing live networks. It therefore gives networks a greater flexibility into mobile communications. It bridges the inter-disciplinary gap in the field as SDR covers two areas of development, namely software development and digital signal processing and the internet. It extends well beyond the simple re-configuration of air interface parameters to cover the whole system from the network to service creation and application development. Reconfigurability entails the pervasive use of software reconfiguration, empowering upgrades or patching of any element of the network and of the services and applications running on it. It cuts across the types of bearer radio systems (Paging to cellular, wireless local area network to microwave, terrestrial to satellite, personal communications to broadcasting) enable the integration of many of today's disparate systems in the same hardware platform. Also it cuts across generation (second to third to fourth). This volume complements the already published volumes 1 and 2 of the Wiley Series in Software Radio. The book discusses the requirements for reconfigurability and then introduces network architectures and functions for reconfigurable terminals. Finally it deals with reconfiguration in the network. The book also provides a comprehensive view on reconfigurability in three very active research projects as CAST, MOBIVAS and TRUST/SCOUT. Key features include: Presents new research in wireless communications Summarises the results of an extensive research program on software defined radios in Europe Provides a comprehensive view on reconfigurability in three very active research projects as CAST (Configurable radio with Advanced Sodftware Technology), MOBIVAS (Downloadable MOBIle Value Added Services through Software Radio and Switching Integrated Platforms), TRUST (Transparently Re-configurable Ubiquitous Terminal) and SCOUT (Smart User-Centric Communciation Environment).

Download or read book Cognitive Radio Architecture written by Joseph Mitola, III and published by John Wiley & Sons. This book was released on 2006-09-14 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: An exciting new technology, described by the one who invented it This is the first book dedicated to cognitive radio, a promising new technology that is poised to revolutionize the telecommunications industry with increased wireless flexibility. Cognitive radio technology integrates computational intelligence into software-defined radio for embedded intelligent agents that adapt to RF environments and user needs. Using this technology, users can more fully exploit the radio spectrum and services available from wireless connectivity. For example, an attempt to send a 10MB e-mail in a zone where carrier charges are high might cause a cognitive radio to alert its user and suggest waiting until getting to the office to use the LAN instead. Cognitive Radio Architecture examines an "ideal cognitive radio" that features autonomous machine learning, computer vision, and spoken or written language perception. The author of this exciting new book is the inventor of the technology and a leader in the field. Following his step-by-step introduction, readers can start building aware/adaptive radios and then make steps towards cognitive radio. After an introduction to adaptive, aware, and cognitive radio, the author develops three major themes in three sections: Foundations Radio Competence User Domain Competence The book makes the design principles of cognitive radio more accessible to students of teleinformatics, as well as to wireless communications systems developers. It therefore embraces the practice of cognitive radio as well as the theory. In particular, the publication develops a cognitive architecture that integrates disparate disciplines, including autonomous machine learning, computer vision, and language perception technologies. In addition, for the convenience of the reader, Web resources introducing key concepts such as speech applications programmer interfaces (APIs) are included. Although still five to ten years away from full deployment, telecommunications giants and research labs around the world are already dedicating R&D to this new technology. Telecommunications engineers as well as advanced undergraduate and graduate students can learn the promising possibilities of this innovative technology from the one who invented it.
