一种基于chan算法的tdoa定定位的gdop程序源码 (Given the positioning gdop program source code algorithm TDOA based chan)

说明：  检测两个输入信号的相位差。DFT_main函数中模拟了三种曲线，并对比了计算出的相位与理论相位的误差。(Detect the phase difference between two input signals. Three kinds of curves are simulated in DFT main function, and the errors between calculated phase and theoretical phase are compared.)

c语言实现互相关函数进而实现两个信号时延计算(c language cross-correlation function and then the two signal delay calculation)

控制改变工作频率，可更改，可移植性强，可对多种器件进行操作(Control to change the operating frequency can be changed, portability, and can operate on a variety of devices)

三层平板介质光波导计算，该平板波导主要由3层均匀介质构成，中间的芯层折射率为n1，厚度为d，芯区生长在折射率为n2的衬底上，芯区上面的覆盖层折射率为n3。这里考虑的是n1大于n2大于n3。(Three-layer flat-plate dielectric waveguide, the flat waveguide is composed of three uniform media, the refractive index of the middle layer is n1, the thickness is d, the core area is grown on the substrate with refractive index n2, The refractive index of the layer is n3. It is considered here that n1 is greater than n2 and greater than n3.)

说明：  一个指纹识别的matlab源码，功能很好很强大(A fingerprint recognition matlab source code, function very very strong)

关于ofdm的一个程序，OFDM的仿真，可以用flipdim函数构造对称共轭矩阵(A program on ofdm, OFDM simulation, you can use flipdim conjugate symmetric matrix function construction)
