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。
This paper introduces the concept of fully complementary code, and gives a method of generating complete complementary code and a new extension method. The performance of CDMA system based on fully complementary code in additive white Gaussian noise channel and Rayleigh channel The simulation is carried out and compared with the traditional CDMA system. The simulation results show that the CDMA system based on complete complementary code has good performance against multiple access interference.
