Fourier

本程序利用K-wave实现了用一维线性阵列探测器采集到的光声信号数据完成2维光声图像重建。(This program implements the use of K-wave one-dimensional linear array detector photoacoustic signals collected data to complete two-dimensional photoacoustic image reconstruction.)

混沌系统加密解密 结合DNA编码的加减法操作(Chaotic system with DNA encoding the encryption and decryption operations of addition and subtraction)

一个FFT改进版程序，使用kaiser窗；可以方便地打出信号的频谱包络，以及算出SNR/SINAD/THD/SFDR等各种数值。工程上使用非常便利(FFT with Kaiser Wndw, easily plot out the Frequent spetrum and the SNR/SINAD/THD/SFDR performance values)
