对OFDM系统的发送端和接受端信号的频谱进行仿真，还有星座图(On the OFDM system transmitter and the receiving end of the spectrum signal simulation, there are constellation)

说明：  基于原子分解的调频信号参数识别算法估计性能得到了很到的提高(paramater estimation of modulated signal based atomic decomposition)

谱估计法分析随机信号，并对其进行傅里叶变换(Spectral analysis is a tool for signal analysis. Power spectrum estimation is based on limited data looking for signals, the frequency of random process or system components. It said random signal frequency-domain statistical characteristics, there is a clear physical meaning, is an important signal processing research content. Of random signals in the frequency domain, power distribution, that is the power spectral density or power spectrum. Power spectrum estimation has been widely used.)
