摘　　要：本文分析讨论了两种在码间干扰和噪声干扰下误码率的估计方法。第一种是基于泰勒级数展开的分析方法，第二种是基于傅立叶级数展开的分析法，该方法不用码间干扰的矩函数，可用于各种噪声干扰，计算代价低、适用于相干振幅或相位调制技术。In this paper, we analyze and discuss two methods of bit error rate evaluation. First is a method based on Taylor series expansion. The second is a method based on Fouriers series expansion . This method does not make use of the moments of the intersymbol interference. Its computing cost is low and it handles various kinfs of noise, and can be used to coherent amplitude or phase modulation techniques.

关 键 词：码间干扰 误码率 数字传输 信道特性
