This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of the license-free 60-GHz frequency band will allow multi-Gb/s data transmission over short distances. The design of these wireless communication systems strongly depends on the propagation channel. The objective of the thesis focuses on the multidimensionnal channel characterization to quantify at the end the contribution of multi-antenna techniques (MIMO) on the performance of communication. A wideband mm-W frequency channel sounder was developed and has allowed extensive indoor channel measurements. In order to compare experimental results with theoretical value, the ray tracing tool was improved. Taking into account the diffraction that takes place at the top of a rectangular obstacle, a new method based on a hybrid uniform theory of diffraction-physical optics has been proposed and validated. Experimental results had also allowed to quantify the diffuse parameters for materials usually found in indoor environments. It was shown that introducing the contribution of diffuse scattering improves the accuracy of the RT tool unlike what it can be found in the literature where an average diffuse scattering parameter is proposed for a given environment. Finally, based on the channel measurements, the performance of IEEE 802.15.3c MIMO-OFDM systems was performed and the results show that the use of antennas array at both the transmitter and receiver side could increase both the throughput by a factor of 3.7 and the communication distance by 1 meter.

Download or read book Propagation Channel Characterization Parameter Estimation and Modeling for Wireless Communications written by Xuefeng Yin and published by John Wiley & Sons. This book was released on 2016-09-13 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive reference giving a thorough explanation of propagation mechanisms, channel characteristics results, measurement approaches and the modelling of channels Thoroughly covering channel characteristics and parameters, this book provides the knowledge needed to design various wireless systems, such as cellular communication systems, RFID and ad hoc wireless communication systems. It gives a detailed introduction to aspects of channels before presenting the novel estimation and modelling techniques which can be used to achieve accurate models. To systematically guide readers through the topic, the book is organised in three distinct parts. The first part covers the fundamentals of the characterization of propagation channels, including the conventional single-input single-output (SISO) propagation channel characterization as well as its extension to multiple-input multiple-output (MIMO) cases. Part two focuses on channel measurements and channel data post-processing. Wideband channel measurements are introduced, including the equipment, technology and advantages and disadvantages of different data acquisition schemes. The channel parameter estimation methods are then presented, which include conventional spectral-based estimation, the specular-path-model based high-resolution method, and the newly derived power spectrum estimation methods. Measurement results are used to compare the performance of the different estimation methods. The third part gives a complete introduction to different modelling approaches. Among them, both scattering theoretical channel modelling and measurement-based channel modelling approaches are detailed. This part also approaches how to utilize these two modelling approaches to investigate wireless channels for conventional cellular systems and some new emerging communication systems. This three-part approach means the book caters for the requirements of the audiences at different levels, including readers needing introductory knowledge, engineers who are looking for more advanced understanding, and expert researchers in wireless system design as a reference. Presents technical explanations, illustrated with examples of the theory in practice Discusses results applied to 4G communication systems and other emerging communication systems, such as relay, CoMP, and vehicle-to-vehicle rapid time-variant channels Can be used as comprehensive tutorial for students or a complete reference for engineers in industry Includes selected illustrations in color Program downloads available for readers Companion website with program downloads for readers and presentation slides and solution manual for instructors Essential reading for Graduate students and researchers interested in the characteristics of propagation channel, or who work in areas related to physical layer architectures, air interfaces, navigation, and wireless sensing

Download or read book Handbook of Radio and Optical Networks Convergence written by Tetsuya Kawanishi and published by Springer Nature. This book was released on 2024-11-04 with total page 1711 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook provides comprehensive knowledge on device and system technologies for seamlessly integrated networks of various types of transmission media such as optical fibers and millimeter and THz waves to offer super high-speed data link service everywhere. The seamless integration of the knowledge of radio and optical technologies is needed to construct wired and wireless seamless networks. High-frequency bands such as millimeter-wave and THz-wave bands where super wideband spectra are available can offer high-speed data transmission and high-resolution sensing. However, the expected coverage is limited due to large wave propagation loss. Thus, convergence of radio and optical links is indispensable to construct worldwide networks. The radio and optical technologies share the same physics and are closely related to each other but have been developed independently. Therefore, there is a big gap between these two fields. Bridging the two fields, this handbook is also intended as a common platform to design integrated networks consisting of wireless and wired links. Full coverage of wireless and wired convergence fields ranging from basics of device and transmission media to applications allows the reader to efficiently access all the important references in this single handbook. Further, it also showcases state-of-the-art technology and cases of its use.

This book was released on 2018-08-02 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past few decades, wireless access networks have evolved extensively to support the tremendous growth of consumer traffic. This superlative growth of data consumption has come about due to several reasons, such as evolution of the consumer devices, the types of telephone and smartphone being used, convergence of services, digitisation of economic transactions, tele-education, telemedicine, m-commerce, virtual reality office, social media, e-governance, e-security, to name but a few. Not only has the society transformed to a digital world, but also the expectations from the services provided have increased many folds. The last mile/meters of delivery of all e-services is now required to be wireless. It has always been known that wireless links are the bottleneck to providing high data rates and high quality of service. Several wireless signalling and performance analysis techniques to overcome the hurdles of wireless channels have been developed over the last decade, and these are fuelling the evolution of 4G towards 5G. Evolution of Air Interface Towards 5G attempts to bring out some of the important developments that are contributing towards such growth.
