Performance Evaluation of Bpn Based Viterbi Decoder for Decoding 2-bit and 3-bit Errors

In communication, convolution codes are extensively used for reliable data communication at receiver’s end the coded messages are decoded with Viterbi Decoders. However when the channel is noisy decoding becomes computationally complex even with enhanced Viterbi Decoder, hence it necessitates an efficient computationally less complex decoders. In this paper Viterbi Decoders are realized in BPN, performance of the decoder for 2-bit errors and 3-bit errors is studied in terms of accuracy. It is found that Back Propagation Network (BPN) based Viterbi Decoder functions well for both 2-bit and 3-bit errors even after shrinking the hidden layer architecture.
