Patent ID: 8861653

Claim:
A decoder, comprising: an a priori decoding component configured to: obtain a plurality of coded data bits from a bit stream that is convolutional coded according to generator polynomials G 0 =1+D 3 +D 4 and G 1 =1+D+D 3 +D 4 , where ‘D’ represents a data stream and where each information bit U k−1 is determinable from a modulo 2 sum of coded data bits C 2k and C 2k+1 , where ‘k’ represents an index value between 0 and a number ‘n’ based on a number of bits in a burst of the bit stream; and determine a priori information associated with each information bit U k−1 based at least in part on the modulo 2 sum of the coded data bits C 2k and C 2k+1 ; and a Viterbi decoding component configured to employ the a priori information in calculating a binary value for each information bit.
