Apparatus and method for using adaptive algorithms to exploit sparsity in target weight vectors in an adaptive channel equalizer

摘要

Apparatus 32 and method for using an adaptive algorithm that exploits the sparsity of target weight vectors of an adaptive channel equalizer 300 are disclosed. The adaptive algorithm includes the selected value of the preceding and the selected value of the cost function. The present invention includes algorithms adapted to calculate adaptive equalizer coefficients for lean transmission channels. The present invention provides lean Minimum Mean Square (LMS) algorithms and lean algorithms in the form of a dilute phase-count algorithm (CMA) and a dilute decision-directed (DD) algorithm.
