Neural-network-curve-fitting

本代码是关于多天线技术空时块编码的通信系统仿真源程序，其中包括QPSK调制，QPSK解调，FFT,IFFT，STBC等模块,并给出误码率计算和性能仿真图。(The code is on the multi-antenna space-time block coding techniques of communication system simulation source code, including QPSK modulation, QPSK demodulation, FFT, IFFT, STBC and other modules, and gives the bit error rate and performance simulation map.)

可以对探底雷达信号进行认为加噪处理，在通过emd方法去噪处理并画wigb(Think that adding noise can dip radar signal processing, emd method denoising processing and painting wigb the)

是两质量系统matlab中simulink模型(Two quality system matlab simulink model)

说明：  用MUSIC算法实现多径信号的时域时延估计(Time delay estimation of multipath signal using music algorithm)

Real-Time Simulation of Large HVDC-AC Grids

由于一般的功率放大器不是线性的，且动态范围是有限的，所以当OFDM系统内这种变化范围大的信号通过非线性部件时，信号会产生非线性失真。( As the general power amplifier is not linear, and the dynamic range is limited, so that when a large range of variation within an OFDM system, the nonlinear signal components, the signal will produce nonlinear distortion.)
