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. 000149116 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000149116 590__ $$a1.14$$b2009 000149116 591__ $$aTELECOMMUNICATIONS$$b24 / 74 = 0.324$$c2009$$dQ2$$eT1 000149116 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000149116 700__ $$0(orcid)0000-0002-7452-446X$$aGarcia, P.$$uUniversidad de Zaragoza 000149116 700__ $$0(orcid)0000-0001-5293-6132$$aGutierrez, F.$$uUniversidad de Zaragoza 000149116 700__ $$0(orcid)0000-0003-2664-6339$$aValdovinos, A.$$uUniversidad de Zaragoza 000149116 7102_ $$15008$$2800$$aUniversidad de Zaragoza$$bDpto.
