OFDM

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.

算法部分是网上下的，因为应用不同，有所改动，界面程序是我自己加的，很简陋，但是能用，有的地方原程序被注释掉了，是为了保持原有程序的语句，怕删掉以后回不去。运行时注意地址和函数调用格式 (poor)
