A Novel Entropy-Based Decoding Algorithm for a Generalized High-Order Discrete Hidden Markov Model
The optimal state sequence of a generalized High-Order Hidden Markov Model (HHMM) is tracked from a given observational sequence using the classical Viterbi algorithm. This classical algorithm is based on maximum likelihood criterion.

A Novel Method for Decoding Any High-Order Hidden Markov Model
This paper proposes a novel method for decoding any high-order hidden Markov model. First, the high-order hidden Markov model is transformed into an equivalent first-order hidden Markov model by Hadar’s transformation. Next, the optimal state sequence of

Viterbi decoder without carrier recovery
A novel Viterbi algorithm of low complexity without carrier recovery is proposed. The most important modification is that the decision metric for surviving paths is not the cumulated variable but its amplitude. Simulation results of its application to MDPSK and convolutional code show negligible performance loss.
