一个emd分解程序，包括瞬时频率，瞬时幅值，边际谱，Hilbert谱(A emd decomposition process, including instantaneous frequency, instantaneous amplitude, the marginal spectrum, Hilbert spectrum)

本程序实现的是卫星观测定位中移动的卫星对飞行器的有效定位，为了画出飞行器的轨迹图，对原坐标进行插值处理(This program is the satellite observations mobile satellite positioning effective positioning of the aircraft, in order to draw the aircraft trajectory, the original coordinates interpolated)

SM系统matlab程序，传输天线、接收天线数量可调，信号调制方式可调，循环次数可调。最后生成BER性能曲线，并将不同SNR下的BER数据存储到mat文件中。(SM system matlab program, the number of transmission antennas, a receiving antenna is adjustable, adjustable signal modulation scheme, the number of cycles is adjustable. Last generate BER performance curve, and store data in different SNR BER under the mat file.)

利用matla设计的CIC内插滤波器，其中包含了其相应的补偿滤波器。(Matla designed using CIC interpolation filters, which contains the corresponding compensation filter.)

适用于三维定位，和chan算法结合使用,能够提高精度。(Very useful.)

特征惩罚算法 对手竞争学习算法 matlab程序源代码哦(Characteristics of punishment algorithm rival competitive learning algorithm matlab program source code Oh)

ctd data program,salnity,temperature,depth(ctd data program, salnity, temperature, depth)

说明：  经典功率谱估计和三种基于AR模型的功率谱估计matlab代码(Classical power spectrum estimation and three kinds of power spectrum estimation based on AR model matlab code.)

graph structures generation using matlab

说明：  牛顿法解决求根问题。给出所需要求根的方程，以及搜索步长，搜索步数，输出所求得的根值。(Newton s method for solving the root of equation. Inputs: eqation, step lenth, number of steps.)
