重要是实现通过瑞利信道的QPSK的仿真，同时给出了其误码率的仿真(Important thing is to achieve through the Rayleigh channel QPSK simulation, while its error rate is given simulation)

说明：  DSP中两个信号阵列卷积的两种算法。一种是看两个信号得结果，另一种是看结果的每一部分由信号中哪些部分组成。(DSP array convolution of two signals of the two algorithms.)

这是一个基于matlab且运用极大似然估计法对伽马分布进行拟合(This is a matlab-based and the use of maximum likelihood estimation method for gamma distribution fitting)

Image enhancement code using matlab algorithm. Very good performance.

阵列信号处理中有关天线阵列处理的基本程序。％％ARRAY ANTENNA SOFTWARE(signal processing array antenna array processing on the basic procedures. %% ARRAY ANTENNA SOFTWARE)

说明：  em算法的一些重要程序，值得下载参考学习(some of the important procedures em algorithm, it is worth to download the reference)

This is a MATLAB implementation of the SIFT keypoint detector and descriptor (do_gaussian: generate Gaussian scale space of input image do_diffofg: generate Difference of Gaussian (DoG) scale space do_localmax: local extrema as the potential keypoints do_extrefine: refine the keypoints by discarding the ones with low contrast and along an edge do_orientation: compute the orientation of a support region of keypoint do_descriptor: compute the descriptor of a keypoint based on image gradients. do_match: match two images based on the nearest neighbor principle and spatial consistency. do_sift: generate the SIFT descriptors for a given input image. It basically s all the functions above. )

演示MA序列的特征值、自协方差函数和谱密度。程序是开放的，可以修改参数(MA eigenvalues ​ ​ demo sequence, since covariance function and spectral density. The program is open, you can modify the parameters)

求瞬时频率必不可少，MATLAB系统不自带的，下载后放在MATLAB到toolbox，然后在EMD文件夹下，更新MATLAB路径即可。运行emd即可出现频谱分析图。(It is necessary to find the instantaneous frequency. The MATLAB system does not come with it. After downloading, it is placed in the MATLAB to toolbox. Then, under the EMD folder, the MATLAB path can be updated. The spectrum analysis diagram can appear when EMD is run.)
