LPC预测的仿真实现。输出4个图，原始信号和预测信号的波形和语谱。(Simulation of LPC prediction. Output 4 maps, the original signal and prediction signal waveform and language spectrum.)

说明：  《MATLAB时频分析技术及其应用》书籍中的全部章节源代码，保证完整，保证全部。(The source code of all the chapters in the technology and its applications, &quot books&quot MATLAB frequency analysis, to ensure the integrity, to ensure all.)

This m file contains the code mass spring system and its constants

This program compress audio to AAC encoding format . It is developed by visual studio 2010. And written language C++.

实现地图匹配算法，对地图路径进行准确定位。(The realization of the map-matching algorithm, the exact path of the location map.)

说明：  最基本的直接扩频中如何用m语言编写语句产生pn序列(generate pn sequence )

说明：  5、绘制散点图。 对发射和接收信号利用scatterplot函数可显示信号星座图的样子及噪声对信号造成的失真程度。在该图中，横轴代表了信号的同相分量而纵轴代表了正交分量。下面的代码还利用了 对接收信号利用modem.deqammod对象的demodulate方法进行解调。解调结果为包含0到15之间整数的列向量。 (5, draw a scatter plot. The transmitted and received signals can be displayed using a function of the degree of distortion scatterplot like and noise signals caused by the signal constellation of FIG. In this figure, the horizontal axis represents the in-phase component signal and the vertical axis represents the quadrature component. The following code is also used to demodulate the received signal using the method of demodulating modem.deqammod object. Demodulation result is an integer from 0 to 15 comprising a column vector.)
