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

High performance ACS for Viterbi decoder using pipeline T-Algorithm
Alexandria Engineering Journal, 2015 Viterbi algorithm is the most popular algorithm used to decode the convolution code, but its computational complexity increases exponentially with the increasing constraint length due to the large number of Trellis transitions.

Divergence coding for convolutional codes
MATEC Web of Conferences, 2017 In the paper we propose a new coding/decoding on the divergence principle. A new divergent multithreshold decoder (MTD) for convolutional self-orthogonal codes contains two threshold elements.

Truncation effects in Viterbi decoding [PDF]
IEEE Military Communications Conference, 'Bridging the Gap. Interoperability, Survivability, Security', 2003 Practical Viterbi decoders often fall significantly short of full maximum likelihood decoding performance because of survivor truncation effects. In the present work the authors study the tradeoff between truncation length and performance loss for the two most common variations of Viterbi's algorithm: best-state decoding (BSD) and fixed-state decoding (
