Asymptotic Performance Analysis of Hybrid ARQ Protocols in Slotted Direct-Sequence Code-Division Multiple-Access Networks

Abstract

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.
