The work done is based on a previous implementation that was analyzed in order to improve the already existing system performance (area, speed etc.). The Viterbi algorithm is a maximum-likelihood algorithm for decoding of convolution codes. The algorithm tries to find a path of the trellis diagram, where the sequence of output symbols approximately matches… (More)
