An Asynchronous Low Power and High Performance VLSI Architecture for Viterbi Decoder Implemented with Quasi Delay Insensitive Templates [PDF]

open access: yesThe Scientific World Journal, 2015
Convolutional codes are comprehensively used as Forward Error Correction (FEC) codes in digital communication systems. For decoding of convolutional codes at the receiver end, Viterbi decoder is often used to have high priority.

Trellis-Coded Modulation-Enabled Probabilistic Shaping With Simplified Viterbi Decoder for Bandwidth-Limited IMDD Systems

open access: yesIEEE Photonics Journal, 2023
In this article, trellis-coded modulation-enabled probabilistic shaping (TEPS) scheme with a simplified Viterbi decoder is proposed. Trellis-coded modulation (TCM) is embedded in the probabilistic shaping (PS) technique to improve the performance of PS ...

Degenerate Viterbi Decoding [PDF]

open access: yesIEEE Transactions on Information Theory, 2013
We present a decoding algorithm for quantum convolutional codes that finds the class of degenerate errors with the largest probability conditioned on a given error syndrome. The algorithm runs in time linear with the number of qubits. Previous decoding algorithms for quantum convolutional codes optimized the probability over individual errors instead ...

Deep Ensemble of Weighted Viterbi Decoders for Tail-Biting Convolutional Codes

open access: yesEntropy, 2021
Tail-biting convolutional codes extend the classical zero-termination convolutional codes: Both encoding schemes force the equality of start and end states, but under the tail-biting each state is a valid termination.

A New Viterbi-Based Decoding Strategy for Market Risk Tracking: an Application to the Tunisian Foreign Debt Portfolio during 2010-2012 [PDF]

open access: yesStatistika: Statistics and Economy Journal, 2022
In this paper, a novel market risk tracking and prediction strategy is introduced. Our approach takes volatility clustering into account and allows for the possibility of regime shifts in the intra-portfolio's latent correlation structure.
