说明：  MATLAB答题卡识别（GUI，论文） 本课题为基于MATLAB的不变矩答题卡识别。可识别学号，学科，答案，并进行分数统计，以及判断是否及格。后台可设置标准excel答案。经过灰度变换形成灰度图像、二值化处理、图像滤波、边缘检测、hough变换等预处理。带GUI交互式界面。(Matlab answer card recognition (GUI, paper) This topic is based on MATLAB moment invariant answer card recognition. Can identify student number, subject, answer, and carry out score statistics, as well as judge whether pass. Standard excel answers can be set in the background. After gray-scale transformation, gray-scale image, binary processing, image filtering, edge detection, Hough transform and other preprocessing are formed. With GUI interactive interface.)

esprit算法是进行高分辨阵列测向地基本算法，它与music算法不同的是它不用进行谱搜索，大大的节省了时间(esprit algorithm is to carry out high-resolution array geotropism test the basic algorithm, it is different music algorithm is its need for spectrum search, significantly saving time)

能量检测，根据以URKOWITZ 在1967年发表的能量检测文章以及Digham 2003、Ghasemi 2007发表的一系列文章为参考， 在AWGN信道中，给定SNR下，先产生一个原始信号（单音或者BPSK基带信号），然后叠加高斯噪声， 再进行能量检测(Energy detection, according to URKOWITZ the energy released in the 1967 test articles, and Digham 2003, Ghasemi 2007 series of articles published as a reference, in the AWGN channel, for a given SNR, the first generating an original signal (mono or BPSK baseband signal), and then superimposed Gaussian noise, then the energy detection)
