一种信道中预去相关CDMA系统的性能

Performance of Pre decorrelating CDMA Systems over A Fading Channel

摘要: 考虑预去相关发射技术的同步码分多址通信系统,在非选择性Rician衰落并受加性白高斯噪声扰动影响的信道中的比特差错概率性能。结果表明,由于衰落的影响使得比特差错概率增加了;比特差错概率随非直通信号幅度的增加而增加。

Abstract: In this paper,the bit error rate of a synchronous CDMA communication system with a pre-decorrelating technique over non-seletive fading channels is considered in additive white noise environment.Results show that the performance become bed because of fading.The bit error rate grows with the increase of the amplitude of non-direct signals.
