The use of forward error correcting codes in the digital communication is used to overcome the data corruptions. Although widely-used, the most popular communications decoding algorithm, the Viterbi algorithm, requires an exponential increase in hardware complexity to achieve greater decode accuracy. The Viterbi decoder that forms the dominant module of TCM decoders are responsible for the overall power consumption. We have analyzed the original T-algorithm with that of the precomputation architecture’s of the T-algorithm. The T-algorithm reduces the complexity of the original viterbi algorithm and reduces the power consumption by 70%.This can be done with the reduction in the negligible clock speed.
