摘要
It is disclosed a method and related circuits for speech coding using Trellis Coded Quantization for encoding of Linear Predictive Coding Coefficienty.;In particular it uses Trellis Coded Quantization for coding Line spectrum Pairs and Reflection Coefficients parameters.;The bit allocation at each quantization step of the Trellis Coded Quantizer is made variable and the quantization error accumulated in quantizing the previous values will be taken in account in the search of the optimum quantization levels of the next values.
