This book was released on 1992 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of voice/data integration in a mixed-media packet radio network employing both ground radio links and SATCOM radio links is investigated. Multi-access strategies are devised to take advantage of different characteristics of both radio channels to better serve the requirements of both traffic types. Code-division multiple-access with movable boundary in the code domain is used in the ground subnetwork to serve the voice traffic and the retransmitted data traffic while framed ALOHA with movable boundary is used on the satellite subnetwork for both data and voice. Based on a Markovian model of the system, a complete analysis of the channel access protocols for both traffic types is given. The performance of the multiple-access schemes used in this mixed-media network is evaluated in terms of voice and data throughput, voice blocking probability, and data delay. It is observed that splitting of retransmission traffic between the satellite and ground subnet may increase the overall data throughput when the voice load is high.

This book was released on 2012-12-06 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Code Division Multiple Access (CDMA) has become one of the main candidates for the next generation of mobile land and satellite communication systems. CDMA is based on spread spectrum techniques, which have been used in military applications for over half a century. Only recently, however, has it been recognised that spread spectrum techniques, combined with some additional steps, can provide higher capacity and better flexibility for the mobile cellular radio communications. Code Division Multiple Access Communications comprises a set of contributions from the most distinguished world scientists in the field. These papers review the basic theory and some of the most important problems related to spread spectrum and CDMA. The topics covered centre on the information theory aspects of CDMA; interference suppression and performance analysis. The material presented in this book summarises the main problems in modern CDMA theory and practice and gives a solid starting point for studying this complex and still challenging field. As such Code Division Multiple Access Communications is essential reading for all researchers and designers working in mobile communication systems and provides an excellent text for a course on the subject.

This book was released on 1998-01-01 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to a request from the Defense Advanced Research Projects Agency, the committee studied a range of issues to help identify what strategies the Department of Defense might follow to meet its need for flexible, rapidly deployable communications systems. Taking into account the military's particular requirements for security, interoperability, and other capabilities as well as the extent to which commercial technology development can be expected to support these and related needs, the book recommends systems and component research as well as organizational changes to help the DOD field state-of-the-art, cost-effective untethered communications systems. In addition to advising DARPA on where its investment in information technology for mobile wireless communications systems can have the greatest impact, the book explores the evolution of wireless technology, the often fruitful synergy between commercial and military research and development efforts, and the technical challenges still to be overcome in making the dream of "anytime, anywhere" communications a reality.
