SYNCHRONIZATION COMMUNICATION SYSTEM

摘要

PURPOSE:To prevent production of pseudo synchronization with respect to the communication system in which a synchronization bit pattern is multiplexed onto coding data outputted from a quantizer and the resulting data are sent, a receiver side detects the synchronization bit pattern to take synchronization. CONSTITUTION:The system is provided with a pseudo synchronization pattern detection section 2 which re-quantizes a quantizer 1 so as to point out a bit location at the detection of a synchronization pattern to revise a bit when the bit pattern simulated to the synchronization bit pattern is detected in coded data outputted from the quantizer 1 thereby revising the bit or quantizing the quantizer 1 so as to revise the bit by predicting the bit location detected by the synchronization bit pattern.
