Examples

Hide and Show Scope

Create a comm.ConstellationDiagram object.

scope = comm.ConstellationDiagram;

Hide the constellation diagram scope window.

if(isVisible(scope))
    hide(scope)
end

Show the constellation diagram scope window.

if(~isVisible(scope))
    show(scope)
end

Hide the constellation diagram scope window again.

if(isVisible(scope))
    hide(scope)
end

Hide and Show Constellation Diagram

Generate a 16-QAM reference constellation and a signal to display.

M = 16;
xRef = (0:M-1)';
refConst = qammod(xRef,M);
signal = randi([0 M-1],1000,1);

Create a constellation diagram System object™, specifying the constellation reference points and axes limits using name-value pairs.

scope = comm.ConstellationDiagram('ReferenceConstellation',refConst, ...
    'XLimits',[-4 4],'YLimits',[-4 4]);

Modulate the random data signal using QAM. Add Gaussian white noise to the QAM symbols. Display the QAM symbols and noisy symbols with the constellation diagram object.

sym = qammod(signal,M);
rcv = awgn(sym,20,'measured');
scope([sym rcv]);

Hide the constellation diagram scope window.

if(isVisible(scope))
    hide(scope)
end

Show the constellation diagram scope window.

if(~isVisible(scope))
    show(scope)
end

Clear the workspace variables.

clear scope sym rcv M refConst signal xRef
