高斯牛顿函数的最优化算法matlab源程序。。。(Function by the Gauss-Newton optimization algorithm matlab source code)

用于计算两组变量之间的同步指数，用matlab编写的代码(Two sets of variables used to calculate the index synchronization between the code written in matlab)

分别绘制ASCAT，海洋2号和两者共同观测的覆盖率在同一图中(Were plotted ASCAT, Ocean 2 and the coverage of both common observation in the same figure)

本程序主要通过EMD和hilbert求IMF，作出HHT归一化能量谱图（三维图），边际谱图和瞬时能量图，并做完备性验证(The program primarily through EMD and hilbert seek IMF, to HHT normalized energy spectrum (three-dimensional map), the marginal spectrum and the instantaneous energy map, and do a complete validation)

对正弦信号进行傅里叶变换，并对比不同的信号长度与采样频率对结果的影响(Fourier transform of the sinusoidal signal and contrast the different length of the signal with the sampling frequency results)

该程序将常用的线性码、循环码、汉明码、BCH码等，配上常用的二进制相键控调制BPSK搭建成仿真系统，对它们的传输特性进行了仿真！(The program commonly used linear codes, cyclic codes, Hamming, BCH codes, coupled with the commonly used binary phase shift keying modulation BPSK built into the simulation system for their transmission characteristics are simulated!)
