该代码实现了“大津法”，也就是最大类间方差算法，完全由本人自己编写，结果很好。(The code of the " Otsu method" , which is the Otsu algorithm, written entirely by my own, good results.)

阵列信号处理中自适应波束优化准则之一ASC旁瓣相消 MSE准则(Array Signal Processing ASC adaptive beam sidelobe canceller MSE criterion of optimization criteria)

横向自适应滤波器和判决反馈自适应均衡器误码曲线学习比较

收集在一起的学习matlab Gui设计的学习资料，讲解很详细清楚(Gather together to learn matlab Gui design learning materials, to explain very detailed and clear)

fs = 8000 t = (0:1/fs:1). x1 = cos(2*pi*t*300) x2 = cos(2*pi*t*400) ha = phased.ULA( NumElements ,10, ElementSpacing ,1) ha.Element.FrequencyRange = [100e6 300e6] fc = 150e6 x = collectPlaneWave(ha,[x1 x2],[10 20 45 60] ,fc) rng default noise = 0.1/sqrt(2)*(randn(size(x))+1i*randn(size(x))) hdoa = phased.ESPRITEstimator( SensorArray ,ha,... OperatingFrequency ,fc) doas = step(hdoa,x+noise) az = broadside2az(sort(doas),[20 60])

主要是MIMO-OFDM系统的C++语言实现，简单实用，值得一看。(This is a C++ language of MIMO-OFDM system, simple and practical, worth a visit.)

转载leiqui的内容，QPSK仿真内容，附件模型是根据书上的原理图进行组织，每一模块都呈现。例如I/Q分路，调制，解调，判决等。 (Reproduced leiqui content, QPSK simulation content, attachment model is based on the book is organized on the diagram, each module are presented. Such as I/Q splitter, modulation, demodulation, judgments.)
