Abstract:
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 multiplying the result by said slicer error; an adaptation selection module coupled to said slicer; wherein said adaptation selection module is to receive information associated with a convergence status of said equalizer from said slicer and to select either said first adaptation module or a second adaptation module to adapt said interference canceller; wherein said second adaptation module is to adapt said interference canceller at a higher signal-to-noise ratio (SNR) relative to said first adaptation module after said equalizer converges; and wherein said adaptation transition between said first and second adaptation modules use a same set of coefficients for the interference canceller.
