| 20100177668 | UNITED AFEC AND METHOD THEREOF, AND TDD RADIO REPEATER APPARATUS USING THE SAME - 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. | 07-15-2010 |
| 20090207776 | Adaptive Forward Error Corrector And Method Thereof, And TDD Radio Repeating Apparatus Using The Same - An adaptive feedback estimation and cancellation (AFEC) apparatus includes: a controller for generating and outputting control information by using a synchronization signal from an external synchronization acquisition unit and base station information, in order to remove a feedback signal that exists in a forward/reverse repeater signal to be repeated and then send the forward/reverse repeater signal; a first feedback prediction canceller for adaptively removing a feedback signal that exists in the forward repeater signal based on the control information from the controller and automatically adjusting the gain of the forward repeater signal; and a second feedback prediction canceller for adaptively removing a feedback signal that exists in the reverse repeater signal based on the control information from the controller and automatically controlling the gain of the reverse repeater signal. | 08-20-2009 |
