ABSTRACT:
A simplified transition detector identifies phase reversal without relying upon complex correlation relationships or trellis techniques. Two correlation signals are obtained using tones with a phase difference of .pi./2. Zero-crossing information on the two correlation signals is used to detect phase reversal.
