EXPLOITING KNOWN PADDING DATA TO IMPROVE BLOCK DECODE SUCCESS RATE

摘要

A method and system of decoding a ccnvolutionally encoded data block having known padding bits. A Viterbi decoder is constrained to a state corresponding to k−1 padding bits immediately adjacent to data bits of the data block, where k is a constraint length of a convolution encoder used to encode the data block. Symbols of the encoded data block that have influence only from the padding bits are discarded.
