延伸阅读
线性预测编码 用线性预测原理降低编码数码率的信号编码。它主要用于话音、图像和遥测信号的编码。信号一般是时间的函数,具有前后相关联的性质(相关性),后面的信号是由前面的信号渐变而来的,知道前面的信号就能对即将到来的信号进行预测。前后信号相关性越强,这种预测就越准确。预测编码不是对连续的信号直接采样后编码(见脉码调制),而是先根据信号的相关性测算,把测算用的参数以及测算值和真实值的误差进行编码。在一般情况下它的编码数码率比直接采样后编码的数码率低得多。 线性预测 预测之前先把信号离散化(采样)。设过去的已知采样值序列为sn-1,sn-2,...,则可用下式预测即将到来的(现时)样值sn
