说明：  一种有效的滤波算法，通过比较特定区域内的像素点的邻域均值来进行图像的去噪滤波。(An effective filtering algorithm, by comparing the particular pixel within the region to the neighborhood mean filter for image denoising.)

对原始语音进行上采样和下采样，分析对比他们的时域图和频谱图。最后对比原始语音、75HZ激励、150HZ激励以及噪声激励下的效果(SOME SIMPLE MANIPULATIONS OF SOUND USING DIGITAL SIGNAL PROCESSING The original sound and its spectrogram Downsampling the waveform downsampling Upsampling the waveform Linear filtering the waveform Original speech The source-filter model of speech Speech with 75-Hz excitation Speech with 150-Hz excitation Speech with noise excitation)

光伏电池模型，最大功率跟踪，输出功率电压电流特性曲线(Photovoltaic cell model, maximum power point tracking)

海明马德matlab仿真，还比较好用!编译码程序都放在了一起，信道参数也在程序中体现了 ！(海明马德matlab simulation, is still relatively easy to use! Codec programs together on, channel parameters are also embodies the process!)
