Abstract
A method signal for decoding in a diversity reception system can include converting the received RF signal into a plurality of digital baseband signals; phase aligning the plurality of digital baseband signals to produce a plurality of phase aligned digital baseband signals; determining a plurality of error terms from the plurality of phase aligned digital baseband signals; one of which corresponding to one of the plurality of phase aligned digital baseband signals; determining a plurality of weighting factors for the plurality of error terms based on characteristics of the plurality of digital baseband signals, one of which corresponding to one of the plurality of error terms; applying the plurality of weighting factors to the plurality of error terms to produce a plurality of weighted error terms; summing the plurality of weighted error terms to produce an error term for decoding.
