得到可观测到的卫星的坐标后，遍历所有的4个卫星组合（4点定位）计算GDOP。(To obtain the coordinates of the satellite can be observed after traversing all combinations of four satellites (4-point positioning) Calculation GDOP.)

The Wavelet Neural Network This is simple example for using of modified Morlet neural network. Levenberg-Marquardt with numerical Jacobian calculation implemented. Easy to use with other optimization algorithem e.g GA,PSO, etc. The function "xox_lm" may be useful for other optimization problem easily. The function "xox_jacobian" may be useful for Jacobian calculation easily. The function "NN_fcn" may be used by the evolutionary based neural network. The activation function "modified Morlet" will be replaceable by others.

AR自适应模型的参数估计，包括模型的参数和阶数(AR adaptive model parameter estimates, including model parameters and the order)

本程序是自己编写的关于广义相关法的时延估计，对于初学者很有用，里边还有关于改变中心频率对时延估计的影响部分(This procedure is to write your own delay estimation on generalized correlation method, useful for beginners, and inside there are about changing the center frequency delay estimation section)
