Melhorar o desempenho geral da comunicação de voz confiável em rádios de ondas ultracurtas em canais muito ruidosos é de grande importância e uso prático. Um algoritmo iterativo conjunto de (des)codificação e (des)modulação (des)modulação (JSCCM) do canal fonte é proposto para ITU-T Rec.G.729EV, explorando a redundância residual e passando informações suaves por todo o receptor enquanto introduz um global sistemático processo de iteração. Sendo totalmente compatível com a estrutura existente do transmissor, o algoritmo proposto não introduz expansão adicional de largura de banda e atraso de transmissão. As simulações mostram desempenho substancial na correção de erros e melhoria na qualidade da fala sintetizada em relação aos sistemas convencionais projetados separadamente em canais de atraso e restrição de largura de banda usando o algoritmo JSCCM.

Abstract: Improving the overall performance of reliable speech communication in ultrashort wave radios over very noisy channels is of great importance and practical use. An iterative joint source-channel (de-)coding and (de-)modulation (JSCCM) algorithm is proposed for ITU-T Rec.G.729EV by both exploiting the residual redundancy and passing soft information throughout the receiver while introducing a systematic global iteration process. Being fully compatible with existing transmitter structure, the proposed algorithm does not introduce additional bandwidth expansion and transmission delay. Simulations show substantial error correcting performance and synthesized speech quality improvement over conventional separate designed systems in delay and bandwidth constraint channels by using the JSCCM algorithm.
