| Abstract: | This paper gives a new digital speech coder with real time operation at 9.6Kb/s data rate.The system consists of time-domain harmonic scaling(TDHS)and sub-band coding (SBC)-two different speech compression algorithm.The basic principle of TDHS and several methods of tone detection are described.Finally,several modes of the system executed by DSP in real time are discussed in the paper. |
