摘　　要：文章介绍了完全互补码的概念,给出了一种完全互补码的生成方法和一种新的扩展方法,对基于完全互补码的CDMA系统在加性高斯白噪声信道和瑞利信道中的性能进行了仿真,并与传统CDMA系统进行了分析比较。仿真结果表明:基于完全互补码的CDMA系统具有很好的抗多址干扰的性能。The concept of CC code was introduced, and a method for generating this kind of code was presented. Then a new way for extending CC code was given, and a CDMA system model based on CC code was described. Moreover, the performance simulations for the model in AWGN channel and Rayleigh fading channel were studied, and compared with tradition CDMA system. The simulation results show that the CC-code-based CDMA system can significantly reduce the impact of multiple access interference in a CDMA system.
