Save Constellation Diagram as Picture from Matlab

Matalb able to provide a Constellation Diagram of mulation signal with below command. hScope = comm.ConstellationDiagram; step(hScope,rxSig) But we are not able to save it as a picture. that is because Matlab hide some menubar of the figure. We can show them with below code: shh = get(0,'ShowHiddenHandles'); set(0,'ShowHiddenHandles','On') set(gcf,'menubar','figure') set(gcf,'CloseRequestFcn','closereq') set(gcf,'DefaultLineClipping','Off') set(0,'ShowHiddenHandles',shh) Then you can see the diagram windows looks as below:

BPSK

The equation representing a sine wave is as follows: $$A\cos(2\pi ft +\phi)$$ From above equation, it can be see that we can making changes to the amplitude, frequency, and phase of a sine wave to encode information. However, as frequency is the first derivative of phase, so frequency and phase of the sine wave equation can be collectively referred to as the phase angle. 请输入链接描述 Amplitude Modulation $$\sin(x)\sin(20x)$$ I/Q data RF communication systems use advanced forms of modulation to increase the amount of data that can be transmitted in a given amount of frequency spectrum. BPSK stands for Binary Phase Shift Keying. It is digital modulation technique. The code main from: Jaseem Vp Below is the Matlab code A=5; t=0:.001:1; f1=5; f2=3; N=length(t); ip = rand(1,N)>0.5; x=A.*sin(...
