说明：  GCC时延估计，二次互相关进行估计时延，精确定位(GCC delay estimation, the second cross-correlation to estimate the delay, precise positioning)

pso算法在背包问题中的matlab程序。(pso algorithm in the knapsack problem in the matlab program.)

带有Python界面的EMDEEMDCEEMDAN的程序，做信号处理。(libeemd is a C library for performing the ensemble empirical mode decomposition (EEMD), its complete variant (CEEMDAN) or the regular empirical mode decomposition (EMD). It includes a Python interface called pyeemd. The details of what libeemd actually computes are available as a separate article, which you should read if you are unsure about what EMD, EEMD and CEEMDAN are.)

QR二维码精定位，通过探测三个位置探测图形获得三个坐标，定位准确率90%左右。(QR code precise positioning, through the detection of 3 position detection patterns and then get 3 points, the recognition accuracy is about 90%.)

说明：  通过粒子群优化算法优化PID参数，该算法对pid控制器参数进行整定，pso能够对参数实现优化，且有良好的收敛性。(PSO algorithm tuning PID parameters)

说明：  此程序能应用于陀螺的allen方差的计算(allen Variance calculations used for gyroscope )

说明：  matlab处理音频信号显示音频信号的频谱图，然后滤波，并对滤波前后音频信号的频谱图进行对比，接着对原始音频信号的频谱去掉若干个点与远视音频信号的频谱比较，最后对音频信号的频谱及相位进行三维显示(audio signal processing matlab)
