摘　　要：提出了基于一类新型混沌映射的ＣＤＭＡ扩频通信的原理方案，它可产生满足扩频码要求的一系列混沌二进制序列，理论预测和数值模拟实验吻合得较好，对多用户同时通信的计算机仿真实验取得成功。The Scheme of the principle for CDMA spread spectrum communication systems based on a class of new chaotic mappings is proposed, which can produce chaotic binary sequences to meet the requirement of spread spectrum codes.The experiment agree with the theoretical prediction well, and the computer simulation of the multi user communication is implemented successfully. Moreover, this scheme can overcome some drawbacks of some other proposed ones for chaotic spread spectrum communicatins.
