线性预测器和量化器计算机摸拟结果分析

THE ANALYSIS OF LINEAR PREDICTOR AND QUANTIZED DEVICE BY COMPUTER SIMULATION

本文详细描述了在自适应预测编码器的设计中，线性预测器和量化器的数学摸拟，根据在计算机上摸拟结果分析了各参数对话音的影响．为满足低数码率的要求提出线性预测器采用一阶，量化器为单比特．按照该原则设计研制的４８００比特自适应预测编码器获得了较为满意的话音质量．

This paper describes the mathematical simulation of linear predictor and quantized device in the designing of self-adaption predict coder,and analyses the effect of every parameter on the voice by comprter simulation. In order to meet the need of lower digit code ratio,one-order linear predict and single-bit quantized device are proposed.The 4800 bit self-adapting predicet coder designed on this priciple obtained a comparative good quality.
