摘要
通过对噪声特性的分析，提出了用前置带通滤波器来提高信噪比的方法，改善微弱信号时数据通信的效果。实践证明这个方法是行之有效的。
This paper analyses the characteristics of noise and presents the mernod of promoting S/N by inserting a band-pass pre-filter,which can reduce the Pe in data communication under small signal.Practice shows that the method is profitable.
