Abstract
The Viterbi algorithm(VA) is used to estimate the state transition of discrete-time finite state machine(FSM) that is in an uncorrelated noisy environment. This paper modified the Hamming Network to estimate the state transitions in the finite state machines, and proposed state-parallel and block-parallel Viterbi decoder. The modified Hamming Network(mHN) can perform the decoding of convolutional codes correctly as conventional Viterbi decoder. Furthermore, the complexities of the proposed Viterbi decoder are reduced approximately 10% less than conventional Viterbi decoder, and the processing times are improved approximately 40% more than conventional Viterbi decoder.
