The effect of amplitude and phase error on the performance of receiver is discussed in this paper, and a method of digital correction based on FIR filter is proposed.
本文仔细分析了幅相误差对接收机性能的影响，提出了基于FIR滤波的一种数字域校正的方法。

The method can realize time variant merging automatically, result in simultaneous corrections both for phase and amplitude and avoid the influence of noise.
此方法可自动实现时变拼接，达到相位和振幅同时校正，而且能避免噪声的影响。
