METHOD AND DEVICE FOR FRAME SYNCHRONIZATION IN COMMUNICATION SYSTEMS

A device and method for frame synchronizing in a receiver of a communication system. The frame, transmitted in a signal out of a J-PSK constellation, J≥2, is received including a data sequence, a synchronization marker preceding the data sequence and an acquisition sequence preceding the synchroniza...

Summary:A device and method for frame synchronizing in a receiver of a communication system. The frame, transmitted in a signal out of a J-PSK constellation, J≥2, is received including a data sequence, a synchronization marker preceding the data sequence and an acquisition sequence preceding the synchronization marker, and wherein the synchronization marker is searched by using the acquisition sequence. In addition, a sliding observation window with an extended length, being M≥N can be used. Also, a buffer-based peak detection to find the synchronization marker in a buffered span of received symbols can be used, in addition to list decoding in order to exploit the error detection capability of the channel decoding in the receiver for false alarm detection.
