In this paper, the authors present a novel analytical framework for the study of a multiple access scheme for an ad hoc CDMA network with HARQ error control and MF-LSIC receivers. Unlike most of the literature on Multi-User Detection (MUD), they directly address networking issues. In particular, the authors develop an approach based on renewal and semi-Markov processes, which accurately accounts for the statistical dependencies between interference, coding rate, and performance in a multiple access system. The authors show that their approximate approach can accurately predict throughput and failure rate values, and present results for a specific system, providing useful insight on issues related to the use of HARQ error control and MUD receivers in CDMA ad hoc networks.
