说明：  Matlab使用矩量法求解同轴方腔滤波器腔间耦合系数 求解两个同轴方腔在一定的开窗大小下，确定耦合系数。 首先利用矩量法求解两个同轴方腔的互电容和自电容，详细原理见参考书。 其次再由耦合系数得到两个腔体间耦合窗的大小，这在工程实践中具有很大的作用，耦合系数K的求解详见m文件。(Matlab using the method of moments coaxial cavity filter cavity coupling coefficient between the two coaxial cavity for solving a certain window size, determine the coupling coefficient. First use of moment method to solve two coaxial cavity of the mutual capacitance and self-capacitance, see the detailed principles of reference. Secondly, the coupling coefficients are then the coupling between the two cavities the size of the window, which in engineering practice has a significant role, see the solution coupling coefficient K m file.)

使用matlab来仿真，是卫星导航电文调制，扩频后，产生.mat文件(Matlab simulation satellite navigation message modulation, spreading generate. Mat file)
