Abstract
In this paper, we analyze the throughput and delay performance of a multichannel wireless access protocol using CDMA in the presence of Rayleigh fading. M equal-capacity traffic channels, each of which is assigned a unique orthogonal spreading code, are shared by N mobile users (N/spl ges/M) on the uplink (mobile-to-base station link). Transmission attempts on the uplink are made based on the busy/idle status of the M receivers, which is broadcast by the base station, every slot, on the downlink (base station-to-mobile link). An i.i.d. fading channel model is used to describe the packet success/failure process. Analytical expressions for the average per channel throughput and delay are derived. Simulation results are shown to verify the analysis.
