The present invention provides systems and methods for decoding received messages using a priori characteristics of selected message portions. A message which has been encoded in a particular format, such as a tail-biting convolutional coding, is received and decoded by utilizing the a priori information about the message. In one case, static-type receive bits in a portion of the message, such as a Frame Control Header, are used to reduce the number of trellis states at particular stages of the decoding process. A Viterbi-type decoding process may be employed in either a soft or hard decision mode. Reducing the number of trellis states improves the success rate for message decoding and improves receiver throughput. Power consumption may also be reduced.
