AAC_Encoder_MATLAB

实验了3gpp要求的1/3码率的编译码算法(3gpp test the requirement of 1/3 code rate encoding and decoding algorithms)

在有多普勒扩展的情况下，产生一个FIR滤波器。(Generates a FIR Jakes filter for a given Doppler spread)

计算金属介电常数，用matlab模拟金属介电常数(The calculated metal dielectric constant, using matlab simulation of metal permittivity)

matlab视频读取分帧，显示并存储的代码，并查看属性信息(matlab video reading framing, display and store the code and view property information)

这里上载的都是DUDA模式识别课程中的各种算法的MATLAB实现，可以参考DUDA的《模式识别》课本，很实用(DUDA uploaded here are in pattern recognition program MATLAB implementation of various algorithms, see DUDA of " pattern recognition" of textbooks, very useful)

说明：  Use of DFT or FFT with Matlab

此程序是对齿轮信号进行模拟分析，并通过小波变换进行信号重构(This procedure is to simulate the gear signal analysis and signal reconstruction by wavelet transform)

这个主要设计了一个butterworth 滤波器 实现滤波效果(this is used to lvbo and design a butterworth )

显示图像，利用按键切换图像，可批量查看。MATLAB环境。(Display images, use keys to switch images, available in volume view. MATLAB environment.)
