Abstract

An analytical model for the evaluation of throughput, delay, and stability of asynchronous random-access CDMA systems is presented. A computationally efficient procedure for obtaining throughput and load line curves is derived for a system with a finite number of terminals and exponentially distributed variable-length messages. Numerical results for an example direct-sequence CDMA system are used to demonstrate the analytical procedure. It is shown that stability issues in random-access CDMA are qualitatively similar to those in ALOHA channels, and bistable behavior can be avoided by operating with sufficiently long retransmission delays.
