1. a kind of combination type innovates code book code device, including:

  • The pre-quantization device of first adaptive code this excitation residual error, the pre-quantization device are operated in the transform domain as illustrated;

    Subtractor, deducts the time domain from pre-quantization device from adaptive code this composition and constitutes to produce the second excitation residual error;

    AndCELP innovates code book module, in response to second excitation according to produced by the first adaptive code this excitation residual errorResidual error.
