DPCM编码,简称差值编码，是对模拟信号幅度抽样的差值进行量化编码的调制方式.-DPCM coding, referred to as difference coding is to sample the analog signal amplitude to quantify the difference between the modulation coding.

编程产生一组正态分布的白噪声信号,它的均值和方差以及长度可随意调整。将产生的白噪声信号存入数据文件。 本程序算法用C++语言编写。首先用乘同余法产生均匀分布白噪声，再用变换抽样法转换为高斯分布白噪声 -Program produces a set of normal white noise signal, its mean and variance, and the length can be adjusted. Will produce a white noise signal int

对经过随机噪声信道的AMI码型和CMI码型数字信号进行抽样判决，去除或减弱噪声的干扰-After a random noise on the channel pattern of AMI and CMI sample code digital signal decision to remove or reduce noise interference

线性预测分析是最有效的语音分析技术之一，在语音编码、语音合成、语音识别和说话 人识别等语音处理领域中得到了广泛的应用。语音线性预测的基本思想是：一个语音信号的 抽样值可以用过去若干个取样值的线性组合来逼近。通过使实际语音抽样值与线性预测抽样 值的均方误差达到最小，可以确定唯一的一组线性预测系数。-Linear predictive analysis is one of the most effective voice analysis technology has been wide
