拟合

FH通信系统仿真的作业 拿来跟大家分享一下(FH system)

说明：  matlab函数大全，2003，挺有用的(matlab function Daquan, 2003)

对齿轮箱故障进行提升小波去噪分解重构，准确判断初故障类型(Gearbox fault on lifting wavelet de-noising decomposition and reconstruction and accurately determine the beginning of the fault type)

功放数字预失真算法代码，用Volterra模型对功放建模，Ls算法(Power amplifier digital predistortion algorithm code, using the on the model of power amplifier modeling, Ls algorithm )

利用matlab自带的BP神经网络工具箱对duffing混沌背景模型进行相空间重构与预测，程序中已经给出duffing函数，主函数中也给出了主要注释，方便大家学习交流。(BP' s own use matlab neural network toolbox for duffing chaotic background model and prediction of phase space reconstruction, the program has been given duffing function, the main function also gives the main note, we facilitate learning exchanges.)
