Abstract :
In this paper, a co-channel interference cancellation technique is suggested in order to cancel a feedback interference signal in the wireless communication repeater. And an amplitude, phase and group delay time of the correction signal can be controlled adaptively for optimum cancellation of the feedback interference signal in the proposed cancellation system. The fabricated co-channel interference cancellation system for Korean RFID frequency band (908.5-914 MHz) could obtain the reduced feedback interference signal about 36.4dB
