gardner算法实现码元同步，希望对大家有用!(gardner symbol synchronization algorithm, in the hope that useful!)

关于自适应很好的例子 可以参考参考自适应滤波matlab源程序(Adaptive good example can refer to reference)

说明：  基于MATLAB的源码程序，用来实现读取PPM格式的图像(MATLAB-based source program to read PPM format image)

matlab EMD 降噪方法 m文件 可以分析振动信号(Analysis of vibration signal can be matlab EMD noise reduction method for M documents)

包括最小二乘法、SVM、神经网络、1_k近邻法,使用高阶累积量对MPSK信号进行调制识别，分数阶傅里叶变换计算方面。( Including the least squares method, the SVM, neural networks, 1 _k neighbor method, Using high-order cumulants of MPSK signal modulation recognition, Fractional Fourier transform computing.)

This code is about convolution in gabor domain.

OFDM检测的仿真，通过计算OFDM的归一化4阶累积量，实现OFDM信号的判决，内含升余弦滚降滤波或内插滤波的频谱图(OFDM simulation test, by calculating the normalized OFDM 4th order cumulant, to achieve decision OFDM signal, containing Raised Cosine filter or interpolation filter of the spectrum)

单个印刷数字识别,内有训练样本和测试样本,路径请自行修改.(this is about single figure differentiate)

基于粒子群优化算法和BP神经网络的混合算法，用于求解复杂问题！(The hybrid algorithm of particle swarm optimization algorithm based on BP neural network and, for complex problem solving! )

kalman滤波程序，用于随即过程的估计问题，考虑被估量和观测值的统计特性，适用于平稳和非平稳随即过程(Kalman filtering program, used in the estimation problem of the random process, considering is measured and observed values of statistical properties, is suitable for the stationary and non-stationary random process)
