Method and apparatus for speech coding with trellis - coded quantization for lpc - quantization

摘要

the present invention relates to a linear prediction codec for talked excited by a code book.transmitting, by means of a suitable circuitry, instead of samples of a voice signal.the parameters of a filter and the signal to provide at the entrance of the filter to obtain the removal of the voice signal.it gets a strong reduction of quantity of data to be transmitted.some of the blocks are components, the codec in addition.manufactured using techniques that provide particular advantages in terms of simplicity of calculation and implementation, the level of compression, the rate of error.and the band of transmission of the spoke.
