Vocoder for a mobile terminal using discontinuous transmission |
摘要 |
A mobile terminal includes a vocoder operative in a speech active mode and a speech inactive mode. In speech active mode, the mobile terminal encodes an input signal to generate a coded speech signal. In a speech inactive mode, the vocoder generates comfort noise parameters for transmission by the mobile terminal. During a FACCH-in-progress condition, override logic forces the vocoder into a speech active mode.
