Method and apparatus for switching on and off interference cancellation in a receiver

Abstract

A method of operation of a receiver of a mobile station or a base station of a radio access network and corresponding equipment, the method for use in providing interference cancellation according to a single antenna interference cancellation (SAIC) algorithm without degrading performance in case of little or no interference. The method uses a metric M (having a value that is large when there is strong interference) to gauge whether or not to process an incoming signal burst using a processing path (14a-16a) including a module implementing a SAIC algorithm or instead to process the incoming signal burst using a conventional equalizer processing path (14b-16b). A selector module (13) selects one or the other path based on comparing the metric M with a threshold δ. Various metrics M are possible.
