扩频时隙ALOHA技术捕捉能力及性能分析

Analysis of Capture Capability and Performance of Spread Spectrum Slotted ALOHA

在传统的时隙ALOHA随机多址技术的基础上,提出了与DS/SS-CDMA结合的扩频时隙ALOHA技术,主要对其捕捉性能进行了分析,并且引入马尔可夫模型以便探讨它的吞吐量和时延等参数。

This paper presents the system of spread spectrum slotted ALOHA,which is com-bined by DS/SS-CDMA,and the conventional slotted ALOHA.We analyze the capture capa-bility,throughput and delay of the system using Markov model.
