超声数值模拟

LDA的matlab实现，得出alpaha和beta的值(the procedure to implement Latent Dirichlet Allocation ,the end of this procedure is the value of alpha and beta.)

计算成组滑动的滑窗检测器的最佳门限已知: 击中数N = 128, 组宽n = 8，PF = 10¡ 6，PD = 90 假设以下条件: (a) 信号不起伏 (b) 忽略天线波束调制 1 (c) 计算PD时忽略目标区以外噪声的影响 组门限(第二门限)为K=8 滑窗的门限(第三门限)为L=16 (滑窗中包含的组数为16) 求解: 最佳的KOPT 和LOPT，对这题做了具体仿真实现。需要的朋友，一定知道很有用。(Optimal threshold calculated as group slidable window detector is known: hit number N = 128, the group width n = 8, PF = 106, PD = 90 assuming the following conditions: (a) signal is not undulation ( b) ignore the antenna beam modulation 1 (c) the calculation of PD ignored outside the target area noise of impact group door limit (the second door limit) for K = 8 sliding window of the door limit (third door limit) for L = 16 (sliding window contains group 16) to solve: the best of the KOPT the LOPT, these questions do specific simulation to achieve. A friend in need, we must know to be useful.)

linear discriminan analysis code by matlab

这是一个进行图像轮廓提取和背景提取的matlab仿真，可以运行，是我在做课题时用到的一个小程序(This is a background of the image contour extraction and extraction matlab simulation, you can run, is the topic I am doing a small program used)

new std realesd in the lte newer version to be implemented

传统的DOA估计算法，如MUSIC、ESPRIT算法，都是在假设信号没有相干的情况下求解的，一旦信源信号具有相干性，估计性能会急速下降，所以提出了空间平滑的算法，解决相干信号的波达估计！(The traditional DOA algorithms, such as MUSIC, ESPRIT algorithm, is under the assumption that the signal is not coherent case solving, once the source signal with coherence, estimation performance will fall, so put forward spatial smoothing algorithm, to solve the coherent signal estimation of direction of arrival!)

利用MATLAB实现正交滤波器组的设计。(Use MATLAB to achieve the design of orthogonal filter banks.)

说明：  该程序利用Matlab语言经行编程，实现都测井曲线进行不同尺度的小波变换。(The program uses the Matlab programming language through the line, different implementations log scale wavelet transform.)
