Abstract
A simplified symbol lock detector which uses T/2 spaced signal samples in conjunction with an interpolator to approximate the T/4 shifted signal samples used by conventional symbol lock detectors. The approximated T/4 shifted signal samples are processed by a phase detector prior to input to a threshold detector which indicates proper symbol lock if the lock signal exceeds a predetermined threshold.
