关于车辆声音信号的滤波、能量以及频谱分析(Voice signals on the vehicle filtering, spectral analysis of energy and)

algorithm base for the MACS_VRPTW

这个粒子群算法使用matlab语言编写出来的，可以解决带约束的粒子群算法问题，可以很方便的把问题得到解决(the optimization of constraied pso matlab programmes)

关于ODFM的仿真程序，程序挺多的，有你想要的。(About ODFM simulation program, a lot of programs have what you want.)

精度很高的多椭圆中心提取代码。算法参考论文：A Simple Operator for Very Precise Estimation of Ellipses.

In this directory, we can find the eleven files. The relationship between file name and the number of program written in the book is shown in as follows.

录制一段个人自己的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用窗函数法和双线性变换设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号；最后，设计一个信号处理系统界面。(Record a person s own voice signal, and recording the signal sampling draw sample after the speech signal time-domain waveform and frequency spectrum given filter performance indicators, using a window function method and the bilinear transform filter design and draw the frequency response filter then use the filter of their own design for the signal acquisition filtering, after filtering the signal to draw the time-domain waveform and spectrum, and filtering of signals before and after contrast, analysis of signal changes playback of voice signal Finally, the design of a signal processing system interface.)

多重信号法估计波达方向（DOA）的MATLAB程序(DOA estimation by MUSIC)

4种LDPC的译码算法比较，经测试可以运行。(4 kinds different ldpc decoding algorithm-nomalized/offset/MS and SP )

说明：  信号特征提取matlab实现代码，包括时域、频域、时频域分析。具体使用根据自身需要改进。(Signal feature extraction matlab code, including time domain, frequency domain, time-frequency domain analysis. Specific use according to their own needs to improve.)
