CDMA的多址接入技术

Study of CDMA multiple access technique

CDMA作为一种多址接入技术在无线数据网络中已广为应用 .文中在多码CDMA和单码CDMA研究的基础之上 ,建立了多码CDMA和单码CDMA在分组数据网络中的随机多址接入模型 ,并对其吞吐率特性和归一化时延特性进行了分析 ,在扩频码数目、长度均相等并且匹配滤波器分辨率为

As a multiple access protocol, CDMA is widely used in wireless radio data networks. Through the analysis on multi code CDMA and single code CDMA, a type of random multiple access protocol based on multi code CDMA and single code CDMA in the packet data network is proposed. The throughput performance and delay performance are also given. The result indicates that both multi code CDMA and single code CDMA show the same performance.
