NON-COMPLEX DUAL-CORRELATION PHASE REVERSAL DETECTOR AND METHOD

摘要

A simplified transition detector (100, 300) identifies phase reversal without relying upon complex correlation relationships or trellis techniques. Two correlation signals (304) are obtained using tones with a phase difference of π/2 (302). Zero-crossing information (306) on the two correlation signals (304) is used to detect phase reversal (308).
