第五章载波调制仿真实验 程序仿真 simulingk仿真(Chapter modulation simulation simulation program simulation simulingk)

实现窄带ULA DOA估计 包含music esprit算法及前向空间平滑和前后向空间平滑算法(It can realize the doa estimation of narrowband ULA ,including MUSIC ESPRIT and spatial smoothing methods)

使用matlab生成SOS滤波器，应用于FPGA的一个小型系统，有一定的参考价值(Using MATLAB to generate SOS filter, applied to a small system of FPGA, there is a certain reference value)

FDTD计算二维光子晶体的传输特性，方便进行相关改进器件的模拟。(calculate the reflection of 2D optical crystal by FDTD)

some code use for dsb matlabe

Matlab code for MRC with correlation

参数a,b,n对r=acos(nt+b)的影响，观察菜单和图形的变化，体会相应的程序控制逻辑(The parameters a, b, n r = acos (nt+b) the impact of observed changes in the menu and graphics, the experience of the corresponding program control logic)

读取Yokogawa DL 750, DL 1600 系列 与 DL 7440 示波器的数据. 特点：允许多个通道（trace）的输入，如： [x(:,1:4),x(:,5)]=wvfreadb_moreinput(filename, 1, [1,2,3,4], 1) (loads YT-waveform data from*.wvf file saved by Yokogawa DL 750, DL 1600 series and DL 7440 Oscilloscopes into the variables y (y data) and t (time data). The matrices ind_over and ind_under, illegal contain the indices of overranged data points outside the upper/lower limit of the TDS AD converter and indices of illegal values. advantage：permit several traces, e.g. [x(:,1:4),x(:,5)]=wvfreadb_moreinput(filename, 1, [1,2,3,4], 1) )

最经典的语音降噪算法，MMSE-STSA 保证可用，记得好评(Shor time Spectral Amplitude Minimum Mean Square Error Method for Denoising noisy speech. based on log-Spectral MMSE Ephraim et al (1985))

说明：  基于LMS算法的自适应波束形成算法，可以抑制宽带噪声，并实现目标方位的估计。(The adaptive beamforming algorithm based on LMS algorithm can suppress the wideband noise and realize the target azimuth estimation.)
