ABSTRACT:
A receiver includes an interference canceller circuit which receives a corrupted signal and makes an estimate of the desired signal. Subsequently, an estimate of the interference signal is determined by subtracting the estimated desired signal from a delayed version of the received signal. The receiver forms a final estimate of the desired signal by subtracting the estimated interference from a second delayed version of the received signal.
