ABSTRACT:
A system and method of widening the synchronization range for a discrete multitone multicarrier single pilot tone system includes detecting a first phase error in a received pilot tone; detecting a second phase error in a received second two bit constellation data channel; converting the second phase error to a first quadrant angle between 0-90° and combining the first phase error and the converted phase error to obtain the actual phase error up to and beyond 360°.
