本程序是关于MATALB图象处理应用例子，用MATLAB编程把图象石块的总个数计算出来。(This program is an example on the MATALB image processing applications, using MATLAB programming to the total number of images derived rocks.)

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)

气象通量处理程序，里面有坐标旋转,能量谱分析等代码(Meteorological flux handler coordinate rotation energy spectrum analysis code)

非常好的轨道力学程序包，没事可以试一试，反正不花钱。(orbit mechanics package.. good for learning..just try it.)

说明：  GMSK 信号在衰落信道中的频偏盲估计,学习阶段，大家共同进步(GMSK signal at the frequency of fading channel偏盲estimates, study phase, the common progress of U.S.)
