说明：  该程序是利用对角加载算法求使得信噪比最大时的权矢量，为阵列天线领域(The program is the use of diagonal loading algorithm for making the maximum signal to noise ratio of the weight vector array antenna areas)

ldcp编码解码源程序，用c语言写的，最后生成mex文件用于matlab使用 (ldcp codec source code, using c language, and finally generate mex file for matlab use)

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.

LTE系统中CQI的映射列表，从中可以查出系统工作过程中对应的CQI情况(CQI mapping list LTE system, which the system can find out the work process corresponding CQI case)

用于搜索离散数据的所有峰值，函数内附使用说明(Searching for the all peak values of disperse vector, instruction is incluede in the functin also.)

在matlab上的Asift程序，在原有基础上有所改进，程序可以出色地实现图像的识别，匹配，效果相比SIFT，SURF等有大幅提高(In matlab Asift program improvements based on the original, the program can achieve excellent image recognition, matching, compared to the effect of SIFT, SURF, etc. have greatly improved)
