| Abstract: | In this letter, we present a speech coding, which meets the needs of speech coding in Cooperation Work Efivironment. Waveform Compensation Algorithm is introduced to improve the performance of the proposed coding. Emulation of this speech coding has been realized. Simulation result indicates that not only computational cornplexity and algorithm delay forspeech coding are significantly less than that of the conventional coding, but also proposed coding maintains high speech quality and adapts itself to the features of speech stream. These advantages can make this speech coding potentially useful in the application of collaborative work. |
