Abstract
A device for canceling co-channel interference and a method thereof are provided. The device, in a simulcast receiver for receiving a high definition television (HDTV) signal having a digital format and an analog broadcasting TV signal, includes a detector for detecting a synchronous signal from the analog broadcasting TV signal and outputting a detection signal, a co-channel interference rejection filter for removing co-channel interference from a first input signal including co-channel interference and outputting a second input signal, and a selector for selecting either the first or second input signal according to the detection signal. Therefore, the presence or absence of co-channel interference can be accurately determined regardless of channel environment.
