آشنایی با سیستم های ارتباطات پهنای باند فوق العاده An Introduction to Ultra Wideband Communication Systems

The definitive, end-to-end guide to high-performance UWB system designWith the FCC's approval of new ultra wideband standards, UWB is poised to drive breakthroughs in both commercial and military communications. However, UWB system design is radically different from conventional communications system design, and traditional design guides are insufficientor even misleading. Now, for the first time, there's an authoritative and comprehensive guide to the latest best practices in UWB system design.Authored by leading-edge experts and researchers, Introduction to Ultra Wideband Communication Systems systematically addresses every major issue engineers will face in designing, implementing, testing, and deploying successful systems. The authors cover propagation, antennas, receiver and transmitter implementation, standards and regulations, interference, simulation, modulation and multiple access, networking, applications, and more.Topics includeUWB fundamentals: technology, system components, standards/regulations, and the controversies surrounding UWBNever-before-published techniques for addressing propagation, modeling, and channel simulationUWB antenna designincluding surprising differences between UWB and narrowband systemsEffective transmitter design reflecting UWB's modulation principlesReceiver design for impulse UWB systemsincluding key differences from conventional carrier-based systemsIn-depth coverage of interference, focusing on "peaceful coexistence" between UWB and narrowband radio systemsPractical simulation techniques that avoid unacceptably long simulation timesHow UWB's physical layer capabilities impact the performance and design of upper layersReal-world UWB applications and case studies of existing systemsThis book is the definitive resource for every professional involved with UWB: RF engineers concerned with UWB's impact on radio design; experienced computer and DSP engineers moving into radio communications; systems engineers who must master UWB radio link design; and technical managers who must clearly understand the challenges they'll face in delivering successful systems.
