程序里包括matlab编写的自相关函数、互相关函数、还有离散傅里叶变换-Matlab program includes the preparation of the autocorrelation function, cross correlation function, as well as the discrete Fourier transform

有较好的参考价值，包括广义互相关函数GCC时延估计，相关分析过程的matlab方法。- There are good reference value, Including the generalized cross-correlation function GCC time delay estimation, Correlation analysis process matlab method.

仿真效果非常好，利用matlab GUI实现的串口编程例子，包括广义互相关函数GCC时延估计。- Simulation of the effect is very good, Use serial programming examples matlab GUI implementation, Including the generalized cross-correlation function GCC time delay estimation.
