LMS: Least mean squares (LMS) algorithms is a type of adaptive filter used to mimic a desired filter by finding the filter coefficients that relate to producing the least mean squares of the error signal (difference between the desired and the actual signal)

实现Turbo码的编码以及译码的代码，其中调用了一些子代码。(Turbo codes to achieve the encoding and decoding of the code, which calls some of the sub-code.)

k均值算法用Matlab实现，这个不太确定(k-means algorithm using Matlab achieve, this is not so sure)

This is for histogram equalization

the file contains detection and estimation theroy codes

Real-time Recognition System of Traffic Light in Urban Environment Abstract—detection of arrow traffic light is a focal point research in autonomous vehicle, and in urban environment it is the basic technique. However, most researches mainly concern the circular traffic lights. A novel algorithm is proposed in this paper to resolve the problems of detection and recognition of arrow traffic lights.

matlab7.0基础教程，很全面，适合初学者(matlab7.0 Basic tutorial, very comprehensive, suitable for beginners )

对于高斯脉冲信号，在光纤传输过程中需要考虑群速度色散和交叉相位调制(For the Gaussian pulse signal, in the optical fiber transmission process need to consider the group velocity dispersion and cross phase modulation)

The Wavelet Neural Network This is simple example for using of modified Morlet neural network. Levenberg-Marquardt with numerical Jacobian calculation implemented. Easy to use with other optimization algorithem e.g GA,PSO, etc. The function "xox_lm" may be useful for other optimization problem easily. The function "xox_jacobian" may be useful for Jacobian calculation easily. The function "NN_fcn" may be used by the evolutionary based neural network. The activation function "modified Morlet" will be replaceable by others.

说明：  根据掺镱光纤激光器的速率方程，对激光器工作进行仿真(According to the ytterbium doped fiber laser rate equations，simulate the laser‘s working)
