ABSTRACT:
The present disclosure illustrates that the process of summing an amplitude limited PSK (phase-shift keyed) signal with a one data bit delayed version of that signal and envelope detecting the sum will produce a digital binary data stream that is representative of the original data used to produce the PSK signal in the first place. This approach is distinguished over the prior art approach in that the PSK signal is limited to an amplitude value which is less than the minimum value produced by vectorial summation of noise with the transmitted PSK signal for optimal bit error rate performance.
