ABSTRACT:
A method for reducing interference within a communication system is provided herein. The method comprising the steps of receiving a signal y(n), where y(n) comprises a desired signal, s(n), and a co-channel interfering signal, i(n), wherein s(n) and i(n) are not time-synchronized, converting y(n) into a frequency-domain signal Y(k), calculating a weight vector W(k), wherein W(k) is based on s(n) and i(n), and additionally based on a time offset T existing between s(n) and i(n), and applying W(k) to Y(k) in order to equalize the desired signal, s(n), and reduce co-channel interference i(n).
