ABSTRACT:
A method of performing alternating quadratures differential binary phase shift keying modulation involves limiting phase changes between adjacent in time modulator output symbols to ±90 °, and transmitting modulator input data by 0° and 180° phase differences between non-adjacent in time modulator output symbols.
