ASK Modulation using MATLAB

利用BLACKMANHARRIS窗口设计一个频率采样型FIR滤波器，对一段含噪音的音乐信号进行滤波去噪处理并根据滤波前后的波形和频谱分析滤波性能。(design a frequency-sampling FIR filter utilizing BLACKMANHARRIS window to filter and de-noise some of the music signal,and analysis filtering performance based on waveform and spectral before and after filtering.)

it is phae shift keying

说明：  基于MATLAB的一个电力系统潮流分析程序，效果不错(A MATLAB-based power flow analysis program, good results)

msk的调制解调MATLAB源代码，很不错，值得看看(msk modulation and demodulation MATLAB source code, very good, worth a look)

地心坐标系下的经纬高坐标数据，转换为东北天坐标系下的坐标。输入为经纬高，单位为°。 matlab文件实现，调用函数名为：ECEFtoENV(Geocentric latitude and longitude coordinates of the high-coordinate data is converted to Northeast day coordinate system coordinates. Latitude and longitude input is high, the unit is.)

采用一种新的仿真方法建模与仿真Corraza信道模型：Rayleigh-Normal仿真模型(The method uses a new simulation modeling and simulation Corraza channel model: Rayleigh-Normal simulation model)

说明：  一个雷达回波模拟的matlab程序包,含有在RCS服从卡方分布,瑞利分布(A matlab program package of radar echo simulation, including the distribution of RCS obeying chi square distribution and Rayleigh distribution)
