Fractional-Fourier

LDPC码的matlab仿真程序，希望对大家有用，不客气，(LDPC codes matlab simulation program, in the hope that useful, at worst,)

This function is a very simple application of FFT2 for an image to simulate the effect of bandpass filter with two cut off frequencies. One can easily modify the programme to do the processes for different images, and even implement highpass and lowpass filter

Threshold choice of non-coherent detection of on=-off keying (OOK) signal

说明：  计算时间序列的代码EWT，已经实验过来，能跑的通(Calculate the time series code EWT, has been experimented, can run)

说明：  随机共振是一种新颖的信号降噪方法，适量的噪声能够共振出隐含的特征频率。(SR is a good method to denoise signals.)

Kernel smoothing regression

说明：  内点法的机组组合程序，采用不可行内点启动的原对偶线性规划内点法，采用了稀疏技术(unit commitment program using interior method)

用BP进行非线性动态系统辨识 (BP carried out using nonlinear dynamic system identification)

this is a speaker identification code based on the vocal model of a speaker...

说明：  在MATLAB环境下实现故障分量的提取的算法，用于短路故障的分析和计算。(Fault component extraction algorithm on the MATLAB platform is used to analysis and calculation of short circuit fault.)
