This book was released on 2004-09-01 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the modern battlefield, successful and fast communications is a critical issue. So the need for transmitting information in larger amounts through a military high-speed network increases. Thus the military is seeking viable and effective solutions that may fulfill these requirements in an operational environment. This thesis develops a prototype system based on appropriate low-cost software and hardware solutions. This system is able to detect, analyze and process wireless 802.11g signals. The evaluation of the newly designed system proved that it is effective up to distances of about 400 m with a low packet error rate and could be a useful tool for detecting wireless 802.11g networks. After evaluating the system, it was used for capturing wireless signals so that we would determine the effective transmission range and the data throughput of an 802.11g network. We determined that such a wireless network could be used in military operations because it offers high data rates up to 200 m, while it maintains a connection of the wireless clients for distances up to 400 m. In addition, the performance data collected can be used as guidelines for estimating the expected performance in an operational situation and can provide useful information for successful planning.

Available in PDF, EPUB and Kindle. Book excerpt: As the need to send larger amounts of information increases, the military is looking into viable solutions to push this information throughout the battle space. IEEE 802.1la wireless LAN network presents an attractive high- speed solution by providing data rates up to 54 Mbps. At the same time, wireless LAN introduces increased security risk due to its vulnerability to exploitation of the wireless LAN physical layer. This research will develop a prototype system using low cost hardware and software solution to detect and process wireless IEEE 802.1la signals. Using the prototype, performance data will be collected to determine whether IEEE 802.1 la is a feasible option as a high- speed information network for military use. Additionally, the performance data collected will provide a good basis for predicting the expected performance in an operational scenario and provide valuable information for proper deployment planning.

Download or read book Software Defined Radio written by Walter H.W. Tuttlebee and published by John Wiley & Sons. This book was released on 2003-04-11 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 Psychology of Academic Cheating written by Eric M. Anderman and published by Elsevier. This book was released on 2011-04-28 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Who cheats and why? How do they cheat? What are the consequences? What are the ways of stopping it before it starts? These questions and more are answered in this research based investigation into the nature and circumstances of Academic Cheating. Cheating has always been a problem in academic settings, and with advances in technology (camera cell phones, the internet) and more pressure than ever for students to test well and get into top rated schools, cheating has become epidemic. At the same time, it has been argued, the moral fiber of society as a whole has dampened to find cheating less villainous than it was once regarded. Who cheats? Why do they cheat? and Under what circumstances? Psychology of Academic Cheating looks at personality variables of those likely to cheat, but also the circumstances that make one more likely than not to try cheating. Research on the motivational aspects of cheating, and what research has shown to prevent cheating is discussed across different student populations, ages and settings. Summarizes 50 years of academic cheating trends in K-12 and postsecondary institutions Examines the methodology of academic cheating including the effect of new technologies Reviews and discusses existing theories and research about the motivation behind academic cheating
