Abstract
A transmission method for digital data which is adapted to transmit a predictive residual at every sample and a predictive coefficient and a normalization gain at every data block to thereby provide highly efficient coding and data transmission. An adaptive quantization method suitable for use in the above-mentioned digital data transmission, forms samples into a block and a predetermined multiplication is effected on the sample of each of the blocks to thereby improve the accuracy of the predictive coefficients. A stable operation may be ensured in the adaptive quantizing method by cancelling the subsequent operation when the auto-correlation of input data is not recognized.
