摘要
目的在考虑有一定接入时延情况下，提高码分多址（ＣＤＭＡ）ＡＬＯＨＡ系统的吞吐能力．方法首先建立系统模型，对系统作必要的假设，然后在现有信道负载侦听协议（ＣＬＳＰ）的基础上，采用由中心站计算分组发送概率Ｐｔｒ，并对用户进行必要的控制．结果形成改进的信道负载侦听协议（ＭＣＬＳＰ）．应用此协议对ＣＤＭＡＡＬＯＨＡ系统的吞吐能力进行分析计算．结论采用ＭＣＬＳＰ在较大接入时延情况下。
Aim To increase the throughput of code division multiple access (CDMA) ALOHA system while considering some access delay Methods First to set up system model and make essential assumption for system; then on the basis of channel load sensing protocol (CLSP), to employ divided groups transmiting probability Ptr algorithm at centre station and carry out control for the subscriber Results Throughput of CDMA ALOHA system was analysised and calculated with MCLSP Conclusion In CDMA ALOHA systems employing MCLSP could offer a good throughput characteristic even in the presence of an access delay
