Mat lab code for Amplitude modulation

This is a master thesis on fingerprint identification system. This has matlab code in appendix also.

SAR原始数据，对初学者很有用啊！特别是用matlab读取的很方便(SAR raw data, useful for beginners! Especially matlab read very convenient)

Here we prove that as the tier number and path loss factor increases ,The SIR (Signal to Interference Ratio) also increases! Consider a cellular system with hexagonal cells & cluster size N.

用于雷达信号的产生，并且进行iq正交仿真的文件，文件较小，实用，以matlab应用程序运行，用的2009a版本(For radar signal generation, and for iq orthogonal simulation files, small, practical application runs in matlab, using 2009a version)

里面包含有几个由MP150采集到的ECG、PPG和心率数据，还有一个能显示ECG和PPG信号波形以及频谱的matlab程序，它还能显示经过五点平滑滤波后的ECG和PPG的波形，程序中有注释。(Which contains several by the MP150 collected ECG, PPG and heart rate data, and one can show ECG and PPG signal waveform and spectrum matlab program, it can also display after a five-point smoothing filter after the ECG and PPG waveforms program in the Notes.)

用MATLAB编写的电力系统潮流、短路、暂态源程序(Written by MATLAB power flow, short circuit, transient source)

implementation to calculate the snr of a mri signal

matlab 构造模型，可用于地质构造分析，非常好用！(Matlab tectonic model, and can be used in the analysis of geological structure, is very nice! )

对采集到的信号进行快速傅里叶变换，可以实现对信号频谱分析(The collected signals fast Fourier transform, spectral analysis of the signal can be achieved.)
