The paper has suggested a very simple modification of the algorithm for decoding quasicyclic block codes built on the basis of short convolutional codes. Besides, decoding is executed by the Viterbi ...

The Viterbi algorithm is renowned as a maximum likelihood (ML) decoding technique for convolutional codes. The path memory unit in an (n,k,m) Viterbi Decoder is responsible for keeping track of the ...

Abstract A high speed and low power Viterbi decoder architecture design based on deep pipelined, clock gating and toggle filtering has been presented in this paper. The Add-Compare-Select (ACS) and ...

You can implement FEC techniques for linear block codes (Reed-Solomon codecs) and convolutional codes (Viterbi codecs). To understand this general implementation, look at the hardware behind these ...

Viterbi algorithm is used in the Viterbi decoder for decoding a bit stream that has been encoded using FEC based on a Convolutional code. Below Figure shows the block diagram of Viterbi decoder.

One way to optimize the Viterbi algorithm is to simplify the trellis diagram by reducing the number of states and branches. This can be done by using punctured codes, which skip some of the ...

The decoding in the sliding block decoder was performed simultaneously in forward and backward direction. However, only a 4-state Viterbi decoder was implemented, while for practical 32- or 64-state ...
