说明：  gps定位程序源代码，参考文献为：An Algebraic Solution of the GPS Equations(gps positioning source code, references to: An Algebraic Solution of the GPS Equations)

说明：  用于二元或多元copula 的计算，可以使用(this code is used for calculating copula of bivariate or multivariate cases.)

duffing 算子的仿真算法。 改变程序参数即可得到不同状态下的图形。(duffing operator simulation algorithm. Process parameters change under different conditions can be obtained graphics.)

数字信号传输中，调制是很很重要的一个方面，这个有效代码希望更可以帮助大家(Digital signal transmission, modulation is a very important aspect, the effective code would like to know more can help you)

程序使用了自相关性和互相关性较好的gold码作为扩频序列，直扩，扩频增益设置为31，模拟用户数为4(Program uses a self-correlation and cross-correlation of the better gold code as spreading sequence, direct expansion, spreading gain is set to 31 to simulate the number of users of 4)

说明：  载波同步仿真，使用的是反馈补偿法，接收信号经补偿矩阵，误差提取，环路滤波，相位累加器后反馈回补偿矩阵，稳定后估计相位趋近相位差，存在相位模糊情况。(the simulation of the carrier synchronization)

说明：  可计算任意函数的模糊函数，并由该模糊函数计算出信号的WVD分布，再由tfrwv求得信号的WVD分布，二者进行比较发现相差极小，并提供了一些仿真信号(The fuzzy function of any function can be calculated, and the WVD distribution of the signal can be calculated by the fuzzy function, and then the WVD distribution of the signal can be obtained by tfrwv, and the difference between them is very small)

利用改进型APSO算法可以明显抑制噪声 ，可以直接运行(The improved APSO algorithm can obviously suppress the noise and run directly.)

This system is a whole speaker recognition system.and have database with in it.
