I want to plot an eye dagram of output of modulator.
In Maltab I tried
plot( I, Q), but it doesnt give me the diagram.
In Matlab there is a function
eyediagram(x,n,period,offset,plotstring,h) in Communicatio Toolbox. Unfortunately I dont have the licence and can't use it.
Does anyone know another possobility how to generate the eye diagram?
EDIT 1 Eye diagram with my data
I have added a dely and my new result is
a = 10; eyediagram(bb(a;end), ovs)
sps = 4; data = randi([0 1],1000,1); gmskMod = comm.GMSKModulator('BitInput',true,'PulseLength',5, 'BandwidthTimeProduct' , 0.25, ... 'SamplesPerSymbol',sps); modSigGMSK = gmskMod(data); eyediagram(modSigGMSK,sps,1,sps/2)
