An Example Simulation of Differential GPS

说明：  对sinc函数进行内插后的误差比较（matlab）(Of the sinc function interpolation error after the comparison (matlab))

该程序为matlab源代码，功能为仿真圆环阵的单元选择算法和笔形波束综合(failed to translate)

输入信号五个基于瞬时信息的特征：零中心归一化瞬时幅度功率谱密度的最大值,零中心归一化瞬时幅度绝对值的标准偏差，零中心非弱信号段瞬时相位非线性分量绝对值标准偏差，零中心非弱信号段瞬时相位非线性分量标准偏差，零中心归一化的非弱信号段瞬时频率绝对值的标准偏差，得到识别出的信号类别，本例为2PSK, 4PSK, GMSK, OQPSK, pi/4DQSK中的一个，还可以看Art网络的扩展性。(input signal instantaneous information on five characteristics : In the center is one of the instantaneous rate of the power spectral density of the maximum, is a center to the absolute value of the instantaneous rate of the standard deviation, Non-zero weak signal instantaneous phase of the nonlinear component absolute standard deviation, Non-zero weak signal instantaneous phase of the nonlinear component standard deviation, In the center is one of the non-weak signal of the absolute value of the instantaneous frequency standard deviation, the identification of signal type, The cases of two PSK, 4PSK, GMSK, OQPSK, pi/4DQSK of one, Art can be viewed network scalability.)

说明：  Dijkstra算法找最短路径代码，包括43个案例分析(Dijkstra algorithm to find the shortest path code, including 43 case studies)

Nonlinear Multiresolution Functions

绘制序列及其傅里叶变换的幅值图，并求逆变换。一个matlab程序。(Draw sequences and Fourier amplitude figure, and pray for inverter change. A matlab application. )

三阶龙格库塔，四阶龙格库塔程序，程序完善，通用性强！(The third order runge kutta, fourth order runge kutta procedures, process improvement, strong commonality. )

卫星观测文件伪距单点定位程序。（注：此压缩包没有考入数据文件，请按照函数要求调用函数读取）(Satellite observations file pseudorange single point positioning program. (note: this package is not entered data files, in accordance with the requirements for function calls the function, please read))

目前心率变异性分析已成为当今生物医学工程研究的一个热点，再次我把我分享的心电信号的HRV分析工具上传，更好的服务正在研究这个方向的同行。(heart rate variability analysis tools)
