ABSTRACT:
A system and method enable the fast decoding of a front end of data (e.g., a header) that is convolutionally encoded by treating the front end as a block code. The system and method receive the convolutionally encoded data; extract a finite sized block from the data; and decode the extracted block using a block error correction decoding method. A Viterbi decoder can then be used to decode the remainder of the encoded data based on the decoded block.
