CDMA technique has been largely focused for Wireless Data Network and PCN. ALOHA protocol also has been proven to be effective for Packet Radio Network regardless of low throughput due to channel colisions. In this paper, we evaluate the performance of CDMA_ALOHA scheme, denoted as S_CDMA_ALOHA(Soltted_CDAM_ALOHA) and MS_CDMA_ALOHA(Minislotted_CDMA_ALOHA) system, by analytic and simulation method. The superiority of the CDMA_ALOHA systems over conventional Slotted ALOHA system are clearely demonstrated for throughput, delay and stability performances. The MS_CDMA_ALOHA scheme provides better delay and throughput performance than the S_CDMA_ALOHA scheme.
