摘要
本文研究了扩频技术与ALOHA技术相结合的扩频ALOHA(SAMA)多址接入协议的性能 ,推导了通用的ALOHA系统吞吐性能表达式 .研究结果表明 ,这种宽带随机多址接入技术能够大大提高网络吞吐量 ,显著改善分组传输时延 ,从而有利于满足未来无线数字网络对各种业务支持和服务质量的要求 .
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.
