用matlab实现FFT，不是用matlab自带的函数fft，而是自己重新编程(Matlab implementation with FFT, not the native function with matlab fft, but his re-programming)

A sound source can be localized in a two dimensional plane using the audio recorded at three known microphone locations. Much like a GPS system, Time Difference of Arrival algorithms can be used to determine the difference in time and distance of a sound source to other microphones. With that information a Chan algorithm can be used to determine the X Y coordinates of the originating sound source. To do so, however, you must first provide the XY coordinates of each of the 3 microphones. Note that for faster and simpler calculation one of the microphones should be placed at the origin (0, 0) of you XY plane.

非常强大的信号分解算法，NMD（非线性模态分解），比EMD分解效果更好！具有广阔应用前景！(Very powerful signal decomposition algorithm, NMD (nonlinear mode decomposition), better than the EMD! It has broad application prospects!)

这个是关于purning-fft的算法，即一种改进型的fft。适用于只有一部分有值，并非所有的都有值。(This is on purning-fft algorithm, an improved version of fft. Applies to only part of the value, not all have value.)

说明：  BCH码的仿真，系统自带库函数BCHencode和BCH的code，支持任何非本原BCH和本原BCH码仿真，包含交织模块，支持matlab2017b以上(BCH code simulation, the system comes with library functions BCHencode and BCH code, supports any non-primary BCH and primitive BCH code simulation, including interleaving module, supports matlab2017b and above)
