ABSTRACT:
A receiver includes an input, a correlator, a phase-assisted demodulator, and an output. The input receives a modulated signal and the correlator generates a plurality of correlation values from the received modulated signal The phase-assisted demodulator, coupled to the correlator, selects one of the plurality of correlation values based on relative magnitude and relative phase information of at least a two of the plurality of correlation values. The output provides a demodulated signal, corresponding to the modulated signal, based on the selected one of the plurality of correlation values. The correlation value having the largest magnitude and the correlation value having the second largest magnitude is used in combination with the relative phase information of both correlation values in determining which correlation value corresponds to the correct demodulated symbol.
