Abstract :
The mixed excitation linear prediction (MELP) algorithm has been recently selected as the new federal standard for 2.4 kbit/s coding of speech signals. The authors exploit the average residual inter-frame correlation and the error sensitivities of the bits in a MELP frame to enhance the robustness of the proposed joint MELP turbo coding schemes for operations over Rayleigh fading channels
