摘要:
提出了一种可用于具有大量用户的VSAT卫星通信内向信道的准时隙ALOHA-CDMA接入协议,并给出这种接入协议的信道模型.然后,分析计算了这种信道数据分组成功接收的概率和扩频码间干扰,并对其信道吞吐性能进行分析和仿真.仿真结果表明,这种系统可以显著提高信道吞吐性能和信道利用率.本文提出的准时隙ALOHA-CDMA信道,对于简化组网成本具有现实的意义.
Abstract:
A new k ind o fm ultip le access channel wh ich is called acknow ledgm ent-type random access and code div ision mu ltip le access channel ( ACK-ALOHA-CDMA) is propo sed, wh ich is su itable for inner channe l o fVSAT sate llite communication. First the channelm ode l is g iven, and then the throughput perfo rm ance o f the channel is stud ied. Sim ulation resu lts show tha t a sign ificant perform ance im provem ent can be g ained by the ACK-ALOHA-CDMA channel.
