Generate Eye Diagram of Filtered QPSK Signal

Generate an eyediagram of a filtered QPSK signal. Generate random symbols. Apply QPSK modulation to get a modulated signal. data = randi([0 3],1000,1); modSig = pskmod(data,4,pi/4);

How do you plot an eye diagram?

We take the overall transmit signal and cut parts of length 2T out. Then, we draw all these parts into a single diagram, yielding the eye diagram of the filter. The function drawFullEyeDiagram below uses the same technique to draw a full eye diagram without the time-consuming animation.

How to use eye diagram in Simulink?

A valid eye diagram has two distinct eye crossing points and two distinct eye levels. To open the measurements pane, click on the Eye Measurements button or select Tools > Measurements > Eye Measurements from the toolbar menu.

How to plot constellation diagram in matlab?

Create 32-QAM Constellation Diagram

Use the qammod function to generate the 32-QAM symbols with binary symbol ordering. M = 32; data = 0:M-1; sym = qammod(data,M,'bin'); Plot the constellation. Label the order of the constellation symbols.
