Power collection based adaptive length equalizer
A baseband processing module of a Radio Frequency receiver produces time domain equalizer coefficients and calculates a power threshold based upon a total power of a plurality of taps of the time domain equalizer coefficients. The baseband processing module then performs a plurality of iterations, during each of which it identifies at least one minimum power tap and determines a total power figure based upon zeroing the at least one minimum power tap. When the total power figure compares favorably to the power threshold, the baseband processing module modifies the plurality of taps by zeroing the at least one minimum power tap and continuing iterating. When the total power figure compares unfavorably to the power threshold, the baseband processing module ceases iterating without modifying the plurality of taps by zeroing the at least one minimum power tap and then produces modified time domain equalizer coefficients.
