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.

Power-Efficient Viterbi Decoder Architecture and Field Programmeble Gate Arrays Fpga Implementation

open access: yesElectrica, 2018
A Viterbi decoder systemcomprises a convolutional encoder and Viterbi decoder. In general, the codewords generated from the input series of convolutional encoder arrive at thedecoder through a noisy channel; however, the channel noise can causecorruption

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.

Log-Likelihood Ratio to Improve Hard DecisionViterbi Algorithm [PDF]

open access: yesEngineering and Technology Journal, 2013
Hard decision of Viterbi decoder suffer from the need of high Signal to Noise Ratio (SNR) to achieve reasonable Bit Error Rate (BER). For the purpose of improving the efficiency of its performance, it must increase the constraint length of the code, in ...
