The system distortion is inevitable in wide-band analog quadrature receiver because of the existing of amplitude and phase errors, the performance of receiver become worse.
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。
