Viterbi Decoder Plain Sailing Design for TCM Decoders ijtsrd


Convolutional codes are error correction technique used in noisy channels. Viterbi Algorithm is the most widely used decoding Algorithm, which decodes the sequence in a maximum likelihood sense. But the complexity of the Viterbi decoder increases with the coding rate of the system. Viterbi decoder is the most power hungry module in the Trellis coded modulation system. Viterbi decoding is the best technique for decoding the convolutional codes but it is limited to smaller constraint lengths. The basic building blocks of Viterbi decoder are branch metric unit, add compare and select unit and survivor memory management unit. From the simulation results it is observed that the proposed Viterbi decoder architecture with modified Branch metric calculation can reduce significant amount of computations in order to decrease the hardware usage and to simplify the proceedings.
