Viterbi decoding algorithm for convolutional codes

2015-03-08 08:36    By:qqianluo      View:73      Download:0

convolutional codes k into n-bits of information bits, but k and n is usually small, especially in serial form for transmission delay small. Viterbi decoding on the grid is based on the received sequence in the code to find a distance from the received sequence (or other measures) for a minimum of a...
