基于小波变换神经网络的车流量预测，含程序和数据。小波分析是针对傅里叶变换的不足发展来的，傅里叶变换是信号处理领域中应用最广泛的的一种分析手段，然而它有一个严重不足，就是在变换是抛弃了时间信息，变换结果无法判断某个信号发生的时间，即傅里叶变化在时域中没有分辨能力。小波是一种长度有限，平均值为0的波形，它的特点包括：（1）时域都具有紧支集或近似紧支集；（2）直流分量为零。小波函数是由一个母小波函数经过平移与尺寸伸缩得到，小波分析即把信号分解成一系列小波函数的叠加。(Vehicle flow prediction based on wavelet transform neural network)

是关于OFDM中的PAPR降低方法SLM的MATLAB仿真程序(Is about OFDM PAPR reduction methods in the MATLAB simulation program SLM)

说明：  通带截止频率 =1000Hz，阻带截止频率 =1200Hz，采样频率fs=5000Hz，通带衰减系数 =0.3dB，阻带衰减系数 =40dB。(The digital filter are the digital signal processing important content, the digital filter may divide into IIR and the FIR two main kinds. As for the IIR digital filter design, we need the help of analog prototype filter, and then transform analog filter into digital filter. )

in this program, low resolution s images were converted to high resolution s images.

Denoising Reduces the total-variation of the image. Filters out noise while preserving edges. Textures and fine-scale details are also removed. In this demo the assumption is that a white Gaussian noise is added with priori known (or estimated) noise power (variance). The fidelity term to the input image is calculated automatically so that the power of the noise is reduced.
