生成语音信号s(k)可以表示为 s(k)=∑p=1Paps(k−p)+e(k) 其中,P是滤波器的阶数,ap是滤波器的系数。LDC就是在已知s(k)的情况下获取ap。 求取最常用的方法是最小化真实信号与预测信号之间的均方误差Mean Squared Error,MSE J=E[e2(k)]=E[(s(k)−∑p=1Paps(k−p))2] 要使minE[e2(k)...
linear predictive coding (LPCformulationminimum errorIf one approximates the vocal tract as a series of fixed length tubes (which is equivalent to representing it as an all-pole digital filter) it becomes possible to predict successive samples of the speech wave as linear combinations of previous ...
Linear Predictive Coding Pole Processing (LPCPP)是一种参数化的时频方法,可用于实时识别和跟踪信号中主导频率成分的变化。该方法的实时性指的是离散信号的每个采样瞬间。LPCPP方法进一步处理LPC(线性预测编码)极点,以产生一系列降阶滤波器传递函数来实现主导频率估计。LPCPP是一种基于线性预测编码原理的方法,它通过...
Linear Predictive Coding (LPC) is a popular technique in speech signal processing for efficiently representing the spectral envelope of a speech signal. The MATLAB implementation of LPC involves several steps: pre-emphasis to balance high and low-frequen

Linear predictive coding (LPC) is defined as a digital method for encoding an analog signal in which a particular value is predicted by a linear function of the past values of the signal. It was first proposed as a method for encoding human speech by the United States Department of Defense...
Linear prediction, or linear predictive coding (LPC), is motivated by the fact that the speech signal, at any time instant, can be approximated by a linear combination of its past values. From: Encyclopedia of Physical Science and Technology (Third Edition), 2003 ...
Linear Predictive coding (LPC) is extensively used for analysis and compression of speech signal whereas the Discrete Wavelet Transform is widely preferred for electrocardiogram (ECG) compression. In this paper, we present LPC and wavelet based method to encode ECG signals. The compression algorithm ...
