Abstract
A system, apparatus, method and article to converge a communications system receiver are described. The apparatus may include an interference canceller to receive an interference signal and to produce an adaptive signal. The interference canceller is adapted by a first adaptation module. An equalizer is coupled to the interference canceller. The interference canceller is located before the equalizer. The equalizer receives an input signal formed of a sum of a received input signal and the adaptive signal. A slicer is coupled to the equalizer and to the interference canceller. The slicer receives an equalized version of equalizer coefficients and produces a slicer error. The first adaptation module adapts the interference canceller utilizing a convolution of the interference signal with the equalizer coefficients, and multiplying the results by the slicer error. Other embodiments are described and claimed.
