Produktbeschreibung

Wireless Personal Communications: Advances in Coverage and Capacity present a broad range of topics in wireless communications. The majority of the chapters are relevant to creating higher capacity (spectrally efficient) systems with greater coverage. Topics include adaptive antenna array measurements and algorithm comparisons, Cellular Digital Packet Data deployment guidelines, speech coding techniques, wireless system design methodology, and propagation measurements in hostile or previously unexplored channels.

Wireless Personal Communications: Advances in Coverage and Capacity is organized into three sections. Section I covers novel wireless systems and hardware and focuses on adaptive arrays, wireless hardware methodology, and deployment guidelines for CDPD among other topics. Section II focuses on Code Division Multiple Access (CMDA) and DSP techniques, both of which are used to facilitate more efficient utilization of the spectrum under adverse channel conditions. This section includes techniques for mitigating interference and multipath. Section III deals with propagation and system design issues. Propagation measurements are presented and include results for the channel characteristics at the New York Mercantile Exchange with closely packed people and hostile electromagnetic interference, to measurements of concrete slabs.

Wireless Personal Communications: Advances in Coverage and Capacity serves as an excellent reference source and may be used as a text for advanced courses on the subject.

The wireless industry is growing at a phenomenal rate. Cellular subscribers are increasing at a rate of 45% per year, the market for wireless local loop service is growing at a rate of 42%, and the wireless local area network market is growing at a rate of 61 %. This growth and potential for future growth has motivated companies to commit $20 billion in obtaining 90 MHz of PCS spectrum during the recent FCC auctions in the United States. Obviously spectrum is a costly, but critical, resource. Efficient utilization of this resource is essential for profitable wireless service. To meet this challenge, researchers in wireless communications are tenaciously developing more spectrally efficient modulation techniques, planning tools for efficient communication system layout, and digital signal processing techniques for more robust communications. The papers and lectures presented in this book were originally given at the Sixth Annual Virginia Tech Symposium on Wireless Personal Communications and cover a broad range of topics in wireless communications. The majority of the papers are relevant to creating higher capacity (spectrally efficient) systems with greater coverage. Topics include adaptive antenna array measurements and algorithm comparisons, Cellular Digital Packet Data deployment guidelines, speech coding techniques, wireless system design methodology, and propagation measurements in hostile or previously unexplored channels.
