ABSTRACT:
A digital correlation receiver, having one or more filters, that uses a modified correlation waveform to undo or eliminate the effects of distortion of the received signal. A distorted information signal is applied to a multiplifer for multiplication by a correlation waveform that has been modified to eliminate the distortion present in the received information signal. The product of the information signal and the correlation waveform is then integrated and a bit decision is made at the output of the integrator. The accuracy of the bit decision is enhanced by the elimination of the effects of the signal distortion.
