Abstract

A CDMA unslotted ALOHA system with finite size of queueing buffers is discussed. We introduce an analytical model in which the system is divided into two Markov chains; one is in user part, and the other is in channel part. We analyze the system performance using this analytical model, and evaluate the effect of buffer capacity in terms of the throughput, rejection probability and the average delay
