This book was released on 1989 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: A link throughput-delay analysis is presented for a slotted direct-sequence spread-spectrum multiple-access packet radio network (PRN) operating in the presence of background noise, multiple-access interference, and pulsed jammer noise. The PRN is comprised of an arbitrary number of full-duplex radio units arranged in a paired-off topology. Slotted ALOHA random access is used in conjunction with CDMA for channel access and a type I hybrid ARQ is used for error control. Expression are derived for the link throughput-delay in terms of the channel cutoff rate and capacity. With the friendly objective of maximizing the link throughput, and the enemy objective of minimizing the link throughput, the dependency of the optimal retransmission probability, processing gain, code rate, and jamming fraction on the population size, traffic intensity, bit energy-to-background-noise ratio, is examined in detail. It is shown that properly designed (optimized) PRN using random-access CDMA offers a significantly larger heavy load throughput than a random-access PRN. Theses. (RH).

Download or read book Asymptotic Performance Analysis of Hybrid ARQ Protocols in Slotted Direct-Sequence Code-Division Multiple-Access Networks written by and published by . This book was released on 1990 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the steady-state and dynamic performance of Type 1 Hybrid ARQ protocols in slotted direct sequence code division multiple access networks. The network consists of an arbitrary number of transceivers arranged in a paired off topology. A Markov model is used to derive the throughput delay expressions in terms of the channel cutoff rate and capacity. Network design parameters are identified and their dependency on system parameters is examined in detail. It is shown that, for a given population size, traffic intensity, and bit energy to background noise ratio, there is an optimal probability of retransmission, code rate, and processing gain that maximizes network performance.

This book was released on 1989 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the performance of Type 1 Hybrid ARQ protocols in a slotted direct-sequence code-division multiple-access network operating in a hostile jamming environment. The network consists of an arbitrary number of transceivers arranged in a paired-off topology. The traffic arrival process is derived by means of a Markov model. Through-put delay expressions are derived in terms of the channel cutoff rate and capacity. The effects of jammer state information are discussed. Network design parameters are identified and their dependency on system parameters is examined in detail. It is shown that, for a given population size, traffic density, and bit energy-to-jammer noise ratio, there is an optimal probability of retransmission, code rate, and processing gain that maximizes network performance in the presence of the worst case jamming.
Book Synopsis Multiple Access Protocols by : Raphael Rom
Download or read book Multiple Access Protocols written by Raphael Rom and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer communication networks have come of age. Today, there is hardly any professional, particularly in engineering, that has not been the user of such a network. This proliferation requires the thorough understanding of the behavior of networks by those who are responsible for their operation as well as by those whose task it is to design such networks. This is probably the reason for the large number of books, monographs, and articles treating relevant issues, problems, and solutions in this field. Among all computer network architectures, those based on broadcast mul tiple access channels stand out in their uniqueness. These networks appear naturally in environments requiring user mobility where the use of any fixed wiring is impossible and a wireless channel is the only available option. Because of their desirable characteristics multiple access networks are now used even in environments where a wired point-to-point network could have been installed. The understanding of the operation of multiple access network through their performance analysis is the focus of this book.
