laplacian边缘检 图象进行降噪处理 高斯滤波处理(laplacian edge detection image processing Gaussian filter processing for noise reduction)

A fast customizable function for locating and measuring the peaks in noisy time-series signals. Adjustable parameters allow discrimination of "real" signal peaks from noise and background. Determines the position, height, and width of each peak by least-squares curve-fitting.(A fast customizable function for locating and measuring the peaks in noisy time-series si gnals.

The simulation is a wideband signal is white noise with variance 0.05, single frequency to the frequency of the signal for a single frequency signal 2 to 2 times the adaptive filtering simulation

利用canny算子分割图像，得到修正的跳频信号的二值化时频图(Use canny operator image segmentation, frequency hopping signals corrected binarized time-frequency diagram)

多用户检测的三种子空间方法的仿真对比的是误码率-信噪比性能(Third seed space simulation comparison of multiuser detection method is BER- SNR performance)

原创的，使用vc++实现匀速运动模型（constant velocity）的kalman滤波，可以运行，并有matlab测试程序对滤波结果进行对比。(vc++ constant velocity kalman filter。the matlab m file can obervers the filter results)

经典的GMRES算法，用matlab实现，与matlab自带gmres比对成功(Matlab implementation of the GMRES algorithm)
