simulation of mpsk modulation technick and demonstation of constellation in noisy arean and non-noisy

说明：  小波分析理论与MATLABR2007实现一书的原代码，飞思科技出的.不错的。(Wavelet analysis theory and the realization of a book MATLABR2007 the original code, Synopsys fly out. Good.)

calculates the signal to noise ratio in each subchannel in DMT.(calculates the signal to noise ratio in eac h subchannel in DMT.)

matlab程序，关于模糊神经网络的，编修正函数，五层网络(matlab program, compiled correction function, five network fuzzy neural network)

ofdm系统的基本系统图仿真，包括调制，IFFT，解调，FFT等(The basic system diagram ofdm system simulation, including the modulation, IFFT, demodulation, FFT, etc.)

说明：  单极型倍频SPWM simulink仿真，和同等单极性SPWM相比，相同的开关频率，输出电压THD更低，逆变器输出可使用更小的滤波器，对逆变器体积的降低很有帮助，封装子系统，调制度、载波比和调制频率可自由调节，简单易用。matlab版本：2015b(Compared with the same unipolar SPWM, the same switching frequency and output voltage thd are lower. The output of the inverter can use smaller filters, which is very helpful to reduce the volume of the inverter. The package subsystem, modulation system, carrier ratio and modulation frequency rate can be adjusted freely and easy to use. Matlab version: 2015b)

说明：  DC Motor Speed Modeling in Simulink with input step
