Queuing theory it is a simulation for M/M/1 queue and find its state probabilites in steady state for n=5 and find expected delay time

用matlab分析传统光学系统中加入三次相位掩模板之后所获得的光线像差(Analysis using matlab conventional optical system by adding three phase mask obtained after the aberration of light)

For using this code need to use signal toolbox and general toolbox in your matlab Inpainting using sparse regularization. Consider the pepper image with many missing pixels. Assume that the image is noisy-free. (a) Inpaint the image by using orthogonal wavelet sparsity. (b) Inpaint the image by using a different sparsity prior. Based on the outputs, it is clear that the inpainting result obtain by Sobolev is much better than other methods (i.e. Orthogonal wavelet sparsity and Invariant wavelet sparsity).

绘制互相关信号,采用权向量和迭代次数求滤波器系数.(Drawing cross-correlation signal, weight vector and the iteration number for filter coefficients.)

Dynamic calculation formula, the string into the corresponding formula, dynamic compilation and calculate the results

OFDM channel Using a large number of parallel narrow-band subcarriers instead of a single wide-band carrier to transport information l Advantages » Very easy and efficient in dealing with multi-path » Robust again narrow-band interference

OFDM+QAM Matlab程序，详细中文注释(OFDM+ QAM Matlab procedures, details of Chinese Notes)

说明：  用牛顿迭代的方法，编写程序，是函数迭代的效率提高，比一般的迭代法要好很多(By Newton iteration method, the preparation procedure is to improve the efficiency function iteration, iterative method than the average much better)
