O Algoritmo Viterbi de Saída Suave de direção reversa (um SOVA reverso) é comparado com o SOVA convencional (um SOVA direto) na decodificação de código turbo. Encontramos uma melhoria notável no desempenho do SOVA reverso quando ele não é finalizado, o que acaba sendo devido a um valor de confiabilidade menor, indicando que as condições de terminação do codificador turbo afetam fortemente o desempenho do decodificador SOVA reverso. Também propomos um decodificador SOVA misto em série com hardware eficiente, composto por um decodificador SOVA direto e um decodificador SOVA reverso. Os resultados da simulação mostram que o decodificador SOVA misto em série proposto tem um ganho de codificação de 0.2 dB a 2.0 dB Eb/No sobre o SOVA direto para um exemplo típico de código turbo.

Abstract: The backward direction Soft Output Viterbi Algorithm (a backward SOVA) is compared with the conventional SOVA (a forward SOVA) in turbo code decoding. We find noticeable performance improvement for the backward SOVA when it is not terminated, which turns out to be due to a smaller reliability value, indicating that the termination conditions of the turbo encoder strongly affect the performance of the backward SOVA decoder. We also propose a hardware efficient serially mixed SOVA decoder composed of a forward SOVA decoder and a backward SOVA decoder. Simulation results show that the proposed serially mixed SOVA decoder has a 0.2 dB coding gain at 2.0 dB Eb/No over the forward SOVA for a typical turbo code example.
