摘要
本文首先对影响正交解调结构超宽带接收系统性能的幅相误差作了简要分析 ,随后提出了用复系数FIR滤波器实现整个系统幅相误差校正的方案 ,并推导出一种设计幅相校正FIR滤波器的算法 ,最后给出了一个用此方案实现超宽带系统幅相误差校正的实例 .
This paper first points out which is the main error affecting the performance of ultra wide band quadrature demodulation receiver.Then a method correcting the amplitude and phase errors of UWB quadrature demodulation receiver using complex coefficients digital FIR filters and an algorithm designing the complex coefficients FIR filters is presented,followed by a practical example.
