This book was released on 1986 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, an integrated model of an unslotted spread spectrum multiple access (SSMA) packet radio network is developed. The model combines a detailed model of the radio channel, accounting for the effect of multi-user interference, with a network model that traces the evolution of the number of interfering transmissions and accounts for the half-duplex nature of the radios. A new analysis of the performance of a Viterbi decoder in a packet radio environment allows the model to be used for a system with convolutional Forward Error Correction (FEC) coding. The synchronization process is also analyzed and incorporated into the integrated model. The model makes use of several approximations for tractability. A discrete event simulation is used to validate these approximations. The integrated model leads to numerical results which show the throughput and the probability of success for a packet as a function of the channel level and network level parameters. Specifically, for the radio channel, these parameter include the modulation format, the received signal power, the spread spectrum bandwidth expansion, and the presence or absence of FEC coding. Also, the throughput is found as a function of the synchronization parameters, such as the detection thresholds and correlation times, for several different synchronization circuits and preamble structures. At the network level, the parameters are the traffic rate and the network size. The random access protocols considered include unslotted ALOHA and channel load sensing, which is an extension of carrier sensing to an SSMA network. (jhd).

Book excerpt: In this paper we describe throughput/delay performance results for Spread Spectrum Communication Networks. In previous work we have used a strong independence assumption and an iterative algorithm to generate approximate performance models for (non-spread) multiple access broadcast networks using random access protocols. The model incorporates the effect of buffering and finite populations. In this paper we extend these results to Spread Spectrum Networks capable of Code Division Multiple Access and study the effect of the multi-user threshold and capture.

Available in PDF, EPUB and Kindle. Book excerpt: Primary and secondary multiple-access interference processes are characterized for multi-hop packet radio networks, in which users are assumed to be Poisson-distributed in the plane and to use frequency hopped spread-spectrum signaling with a receiver-oriented assignment of frequency-hopping patterns. The throughput per node and the average forward progress are then evaluated for frequency-hopped multi-hop networks that employ (i) random forward routing with fixed transmission radius (RFR) and(ii) most forward progress routing with fixed transmission radius (MFR). The optimal average number of neighbors and transmission radius are derived for these cases when Reed-Solomon forward-error-control coding with minimum distance decoding or binary convolutional coding with Viterbi decoding is employed.
