Abstract
A correlation demodulator unit (20) having gain normalization includes a correlation demodulator (12) for receiving a signal from a receiver (8). The correlation demodulator has a plurality of correlators (C1-CN) corresponding to a plurality of N correlator outputs. A gain normalizer (15) is coupled to the correlation demodulator for accumulating symbol energy on a symbol by symbol basis for each of the plurality of correlator outputs based upon a current symbol decision providing at least an accumulated value within an accumulator (43) for the plurality of correlators and for normalizing the plurality of N correlator outputs using the accumulated value(s).
