中国移动多媒体广播(CMMB)发射端的MATLAB实现(China Mobile Multimedia Broadcasting (CMMB) transmitter of the MATLAB implementation)

PID用于机器人路径控制的MATLAB程序,路径选择是一个简单的正弦函数.控制参数是速度和角速度.(PID control for robot path MATLAB program, the path of choice is a simple sine function. Control parameter is the speed and angular velocity.)

说明：  希望每一个使用本程序的人都能做到保密，因为这里的许多东西都是相当宝贵的，如果还有别的需要可以单独发邮件给我(hope every one use of the procedures people can be kept confidential, because many things here are very valuable, if there are other needs alone can send an email to)

自己编写的用谱相减，最小均方和维纳滤波实现语音增强的matlab文件(themselves with the preparation of spectral subtraction, the minimum mean square Wiener filtering and enhanced voice document Matlab)

This document is useful for hearing sound classification

1. 给一段原始的语音信号（可以是自己录制的一段语音），加上一频率为3.8kHz的高频余弦噪声和频率为3.6kHz的高频正弦噪声（幅度自己可以选择），用窗函数设计一滤波器（要求最小阻带衰减为50dB）对加噪后的语音信号进行滤波，画出滤波器的频率响应曲线，画出滤波前后的时域图和频谱图。 需要用到的函数： fir1 用窗函数设计FIR滤波器的函数 2. 用GUI设计一界面（如图1所示）完成如下功能： 1） 输入一语音信号，画出语音信号的时域图和频谱图； 2） 对语音信号加噪处理，画出加噪后的时域图和频谱图； 3） 给定滤波器的性能指标，采用几种不同的方法设计滤波器对加噪信后进行滤波，画出各滤波器的频率响应曲线，画出滤波后的时域图和频谱图。 (1. to some of the original speech signal (which can be a voice you record yourself), plus a cosine frequency of 3.8kHz frequency noise and frequency of 3.6kHz frequency sinusoidal noise (in the range that they can choose), with a window function to design a filter (requires a minimum stop band attenuation is 50dB) after adding noise to the speech signal is filtered, the filter frequency response curve to draw, draw diagrams and time-domain spectrum before and after filtering. Need to use the function: function fir1 with window function design FIR filter design 2. Using a GUI interface (Figure 1) complete the following functions: 1) an input speech signal, the speech signal in the time domain to draw graphs and spectrum 2) adding noise to the speech signal processing, draw diagrams and time-domain plus noise spectrum after 3) to set the filter performance, using several different methods designed to filter letter after adding noise filtering, draw the frequency response curve of each )
