中文说明：基于负熵最大的独立分量分析，粒子图像分割及匹配均为自行编制的子例程，搭建OFDM通信系统的框架，BP神经网络用于函数拟合与模式识别，该函数用来计算任意函数的一阶偏导数(数值方法),采用了小波去噪的思想。
English Description：
Independent component analysis based on maximum negentropy, particle image segmentation and match the subroutines are compiled, build the framework of OFDM communication system, fitting and pattern recognition of BP neural network to function, this function is used to calculate the first order partial derivatives of a function (method), using Wavelet denoising of thought.
