Application background
Convolutional codes for encoding and decoding, convolutional codes for signal transmission of the encoding and decoding. Convolutional codes will be K information bits into n bits, but K and N is usually small, especially suitable for transmission in serial form, small delay, in convolutional code decoding process, not only from the time received the code group Extraction & nbsp; information decoding, but also the before or after each time received the code group in extraction of relevant information. And the error correction capability of convolutional codes is enhanced with the increase of the constraint length, and the error rate increases with the increase of the length of the  . Convolutional codes (n, K, m) is mainly used to correct random errors and its symbol and before and after the code has certain constraints, the encoding complexity of available code constraint length mxn. Generally, the minimum distance D shows the convolutionmatlab
