摘要

A Radio Frequency (RF) base Band digital (DBB) compensation Module includes a Digital High Pass Filter (HPFC) used to suppress variation of group delay Distortion produced by the use of High pass filters (HPFS) analogues of low cost in the receiver.The module HPFC reduces frequency of digital Court, established by the HPFS for Frequency Domain responses of real and Imaginary Component Signal providing a First compensation Signal having a First Predetermined value (K1).The HPFC Digital Module adjusts the gain of the step Response of the frequency domain Signal of real and Imaginary Component providing a Second compensation signal that has a Second Predetermined value (K2).
