Abstract:
A digital baseband (DBB) radio frequency (RF) receiver used for receiving and processing a wireless communication signal. The DBB receiver includes a demodulator, first and second analog low pass filters (LPFs), first and second digital gain control circuits, and a digital time domain compensation module which removes group delay variation distortion, introduced by the first and second analog LPFs, from real and imaginary signal components of the communication signal.
