摘要/Abstract

摘要： 多通道随机通信系统的研究是一个新的课题,在以往的研究中,大多集中在固定分配多址接入方式。引入了随机多址接入技术,以便在突发性事件中保持良好的性能,并采用蒙特卡罗方法对CDMA-时隙式非坚持CSMA多用户通信系统在不同因素影响下的网络吞吐量进行了仿真研究。证明了在随机多址接入技术中采用CDMA技术,可以明显改善系统的性能。

Abstract: The multi-users random communication systems is a new researchful subject.Although most researches focus on fixed assignment multiple access method,a random multiple access method to make the systems a well performance on sudden occurrence is introduced in this paper.The factors influencing the performance of the CDMA-CSMA multi-users communication systems have been analyzed by Monte-Carlo simulation.It has been proved that the performance of the communication systems can be improved by using random multiple access method with CDMA.

Key words: DS/CDMA, slot time-nonpersistent CSMA, PLC networks, Bit-Error-Rate
