ABSTRACT:
A frame timing acquisition system and method are provided including a correlator for comparing a first fixed length subsequence of bits of a received bitstream to a predetermined sync word. A CRC check circuit is provided for, in response to the correlator determining that the first fixed length subsequence of bits matches the predetermined sync word, if a third fixed length subsequence of bits of the bitstream is a cyclical redundancy code parity word formed from a second fixed length subsequence of bits of the bitstream. A decision circuit is also provided for identifying boundaries of a frame of the received bitstream in response to the CRC check circuit determining that the third fixed length subsequence of bits is a cyclical redundancy check parity word of the second fixed length subsequence of bits. According to the inventive method and system, a sync word need be identified in only a single slot of the frame in order to acquire the frame timing.
