1.单位冲激信号 单位冲激信号(unit impulse signal)是最基本的信号,定义如下: {δ(t)=0,t≠0∫−∞∞δ(t)dt=1δ[k]={1,k=00,k≠0 代码: k=-10:10;yd=(k==0);stem(k,yd);xlabel('k');ylabel('f[k]');title('unit impulse signal'); 图形: stem()
k-1) + [0; impulse]; x_true(:,k) = x_true(:,k-1) + dx*dt; end...
공유 MATLAB Online에서 열기 다운로드 This code demonstrates using the least mean squares (LMS) algorithm to perform equalization in a communication system. The code generates a QAM-modulated signal, applies a channel impulse response, adds noise, and performs LMS equalization to ...
The purpose of this project is to provide a plot of the Chanel Impulse Response in a use-case scenario of your choice. This folder provides a Matlab function and an example of using it. The "getCIR.m" function imports the CIR values generated by a ray tracer. In our case, it is ...

For this example: KeepUnitsindB(default). Set the passband ripple (Apass) to0.1dB. Set the stopband attenuation for both stopbands (Astop1,Astop2) to75dB. Computing the Filter Coefficients Now that you've specified the filter design, click theDesign Filterbutton to compute the filter coeffi...
The presented codes use a postprocessing step to solve the over-decomposition issues of the signal decomposition algorithm for the wide-band impulse signals. It can be combined with any signal decomposition method. It shows promissing advantages in detecting impulse signal components and can be ...
