| 摘 要： | 基于一个异步直接序列码分多址模型，给出了多址与保密结合的扩频码应具备的条件。为了研究这类扩频码对A-CDMA系统性能的影响，比较了纯随机序列和Gold伪随序列的偶互相关概率分布，得到一些有用结论。

| Abstract: | In this paper, the requirements for the spreading codes combined multiple access and encryption for CDMA systems are presented using asynchronous direct sequence CDMA (A-CDMA) systems as a model.In order to investigate the effect of this soft spreading codes on operational performance of A-CDMA system,the probability distribution functions of the even cross-correlation functions of the purely random sequences and Gold codes is compared. Finally, some useful conclusions are obtained. |
