| Abstract: | The performance of Spread ALOHA Multiple Access (SAMA) is investigated,which combines virtues of pure ALOHA and spread spectrum technique.A more general expression to calculate throughput performance of ALOHA system is obtained.The result of research shows that this multiple access method is one of the promising candidates for the digital wireless network in the future which has the coming demand for supporting various traffics and QoS. |
