Abstract: p-q signals are defined in1,2 as digital signals with first order correlations, they can be generated using parameters p and q. The TTS-MF receiver, developed in1,2, was demonstrated to perform better than the traditional Matched Filter based receiver (STS-MF receiver), in terms of the Bit Error Rate (BER), for positive values of SNR, when the signals are of p-q type. In3, it was demonstrated that the improvement of the TTS-MF receiver over the STS-MF receiver (measured as PRBER), is highly dependent on p + q and the SNR. In this paper, it is demonstrated that practical and statistical digital signals passing through pre-processors and wireless fading channels indeed behave like correlated p-q signals with respect to the applicability of the TTS-MF receiver, with p + q that is quite distant from 1.0. This research thus conclusively lays the required ground and foundation for a new generation of receivers which can deal with practical digital signals, in baseband as well as pass-band communications.
