SOVA-Decoded Serially Concatenated Continuous Phase Modulation System With Markov and Hidden Markov Sources

open access: yesIEEE Access
We design low-complexity bi-directional (forward and backward) modified Soft-Output Viterbi Algorithm (SOVA) decoders to exploit source memory from binary Markov and hidden Markov model (HMM) sources, respectively, for decoding in serially concatenated ...

DESIGN OF TCM DECODERS USING OPTIMIZED VITERBI DECODER

open access: yesInternational Journal of Computer and Communication Technology, 2015
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.

Trellis Decoding for Qudit Stabilizer Codes and Its Application to Qubit Topological Codes

open access: yesIEEE Transactions on Quantum Engineering
Trellis decoders are a general decoding technique first applied to qubit-based quantum error correction codes by Ollivier and Tillich in 2006. Here, we improve the scalability and practicality of their theory, show that it has strong structure, extend ...
