Techniques to converge and adapt a communication system receiver
First Claim
1. An apparatus, comprising:
- an interference canceller to receive an interference signal and to produce an adaptive signal, said interference canceller to be adapted by a first adaptation module;
an equalizer coupled to said interference canceller, said interference canceller is located before said equalizer, said equalizer to receive an input signal formed of a sum of a received input signal and said adaptive signal; and
a slicer coupled to said equalizer and to said interference canceller, said slicer to receive an equalized version of equalizer coefficients and to produce a slicer error;
wherein said first adaptation module is to adapt said interference canceller utilizing a convolution of said interference signal with said equalizer coefficients, and multiplying the result by said slicer error.

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.
