(orcid)0000-0001-9052-9554 Two Step SOVA-Based Decoding Algorithm for Tailbiting Codes 2009 Access copy available to the general public Unrestricted Abstract—In this work we propose a novel decoding algorithm for tailbiting convolutional codes and evaluate its performance over different channels. The proposed method consists on a fixed two-step Viterbi decoding of the received data. In the first step, an estimation of the most likely state is performed based on a SOVA decoding. The second step consists of a conventional Viterbi decoding that employs the state estimated in the previous step as the initial and final states of the trellis. Simulations results show a performance close to that of maximum-likelihood decoding. info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 1.14 2009 TELECOMMUNICATIONS 24 / 74 = 0.324 2009 Q2 T1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Garcia, P.
