Abstract :
The proposed protocol, code grouping multiple access (CGMA), partitions mobile users into virtual code groups to enhance channel utilization for multimedia traffic in a TDD-CDMA environment. CGMA performance has previously been evaluated for both error free and error prone uplink channels. It has been shown that CGMA allocates channel resources more fairly to mobiles while guaranteeing QoS for voice service in comparison to reservation protocol such as first come first serve algorithm. In this paper, the delay performance of CGMA and its fairness in resource distribution are evaluated assuming both uplink and downlink errors. Simulation results confirm that CGMA provides fair resource allocation under both error free as well as with uplink/downlink channel errors.
