United AFEC and method thereof, and TDD radio repeater apparatus using the same

摘要

Provided is a united Adaptive Forward Error Correction (U-AFEC), including: an automatic gain control unit for controlling a gain of forward/backward relay signals; a switching unit for switching the forward/backward relay signals; a forward feedback signal detecting unit for detecting and updating a phase and a size of a feedback signal; a backward feedback signal detecting unit for detecting and updating the phase and the size of the feedback signal; a reverse feedback signal synthesizing unit for generating a reverse feedback signal based on the phase and the size of the feedback signal; a feedback signal removing unit for removing the feedback signal in the forward/backward relay signals and transmitting the forward/backward relay signals to the automatic gain control unit; and a control unit for removing the feedback signal in the forward/backward relay signals and controlling each constituent element.
