Calculate the PSNR of two images

仿真SMI（DMI）算法性能，观察采样快拍数对波束图的影响、接收信号中不包含、包含信号功率逐渐加大对波束图的影响(Simulation SMI (DMI) algorithm performance, the number of snapshots observed sampling effects on the beam diagram, the received signal does not contain, include the gradual increase of the signal power of the beam map)

利用信号的循环平稳特性进行相干源的波达方向估计(DOA Cyclostationarity use of coherent signal source estimates)

说明：  用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图(fft analysis,plot rms spectrum,power density spectrum, etc.)

是一个二乘二天线的多路复用的解码程序，利用Vblast算法来实现的，(Is a second antenna multiplexing二乘decoding procedures, the use of algorithms to achieve the Vblast.)

使用matlab提供的bp网络工具实现手写数字识别。内涵大量测试用手写数字(Bp using matlab network tools available to achieve handwritten numeral recognition. Test a large number of handwritten digital content)

低密度奇偶校验码一,简称码是当前通信领域的热门研究课题之一,是第四代移动通信系统强有力的竞争者。( A low-density parity check codes, referred yard is currently one of the hottest research topics in the field of communications, is the fourth generation mobile communication system strong competitor.)

自己建的一个模型，给大家参考,希望对大家有用。(A matlab model )

说明：  LMS (Least Mean Squares): most basic canonical ANC algo FxLMS (Filtered eXtended Least Mean Squares): adds an additional learned filter for the secondary path signal - signal from cancellation speakers to users ears - to account for phase problems and audio coloration added during practical noise cancellation applications NLMS (Normalized Least Mean Squares): adds simple adaptively updated learning rate on top of LMS to speed convergence. FxNLMS (Normalized Filtered eXtended Least Mean Squares): combines FxLMS and NLMS FuNLMS (Filtered-u Last Mean Squares): adds an additional active LMS filter to FxNLMS to cancel out noise bleeding from the cancellation speaker to the error mic. Fairly robust but convergence not gaurunteed!
