Abstract:
A co-channel interference canceler comprising:a co-channel interference rejection filter for removing co-channel interference from a first input signal to generate a second input signal;a driving signal generator for calculating error rates of said first and second input signals with respect to a reference signal, and generating a driving signal based on the calculated error rates; anda selector for selecting one of said first and second input signals, according to said driving signal,wherein said driving signal generator comprises:a first calculator for calculating a symbol error rate (SER) between said first input signal and a previously stored reference signal, for a first predetermined period to generate a first SER value;a second calculator for calculating an SER between said second input signal and said reference signal, for said first predetermined period to generate a second SER value; anda minimum SER detector for comparing said first SER value with said second SER value to generate the driving signal based on the smaller of said first and second SER values.
