Meningkatkan prestasi keseluruhan komunikasi pertuturan yang boleh dipercayai dalam radio gelombang ultra pendek melalui saluran yang sangat bising adalah sangat penting dan digunakan secara praktikal. Algoritma pengekodan dan (de-)modulasi (JSCCM) sambungan sumber bersama lelaran (de-) dicadangkan untuk ITU-T Rec.G.729EV dengan mengeksploitasi lebihan sisa dan menghantar maklumat lembut ke seluruh penerima sambil memperkenalkan global yang sistematik proses lelaran. Memandangkan serasi sepenuhnya dengan struktur pemancar sedia ada, algoritma yang dicadangkan tidak memperkenalkan pengembangan lebar jalur tambahan dan kelewatan penghantaran. Simulasi menunjukkan prestasi pembetulan ralat yang besar dan peningkatan kualiti pertuturan yang disintesis berbanding sistem reka bentuk berasingan konvensional dalam saluran kelewatan dan kekangan lebar jalur dengan menggunakan algoritma 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.
