将正弦波与宽带噪声分离开来，并提取正弦波信号(The sine wave and separated from the broadband noise, and extract the sine wave signal)

Matlab code for simulation of radar received power versus range. There are other files for additional features like aperture area, swirling objects and pulse integration Happy learning!

说明：  一个ask调制解调的源程序，可以自己添加一些噪声进行仿真分析！(Ask modulation and demodulation of a source, you can add some noise to conduct their own simulation analysis!)

说明：  ofdm仿真程序，包括发射机和接收机两个部分，信道估计，(ofdm simulation program, including the two parts of the transmitter and receiver, channel estimation,)

随机信号功率谱分析 (1) 生成信号，被淹没在在噪声中； (2) 试用周期图法估计信号的功率谱； (3) 选用不同窗，使用修正周期图法估计信号的功率谱； (4) 对一段语音信号，使用LD算法估计其功率谱； (5) 详细列出功率谱估计的步骤和原理。 (power spectral analys)

scattered parameter estimation matlab code

说明：  合成孔径雷达系统MATLALB模拟实现源码。(Synthetic aperture radar system simulation MATLALB realize source.)

说明：  扩频系统中的小实验，具体介绍在文件kuopin_all中有介绍。(spread spectrum system of small experiments, which are detailed in the document kuopin_all were introduced.)

粗糙集属性约简代码，可以运行，可以运用到不同场合，可作为参考(Rough set attribute reduction code can run, can be applied to different occasions, can be used as reference)
