What is constellation in Matlab?

The Constellation Diagram block displays real- and complex-valued floating- and fixed-point signals in the IQ plane. Use this block to perform qualitative and quantitative analysis on modulated single-carrier signals.

Which Matlab function is used to plot the constellation diagram?

You can display the constellation diagram of the transmitted signal using scatterplot .

How do you use a constellation diagram?

Each symbol is encoded as a different combination of amplitude and phase of the carrier, so each symbol is represented by a point on the constellation diagram, called a constellation point. The constellation diagram shows all the possible symbols that can be transmitted by the system as a collection of points.

How to plot QPSK in Matlab?

Plot QPSK Reference Constellation

Determine the reference constellation points. Plot the constellation. Reconfigure the object for bit input and plot the constellation to show the binary values of the Gray-encoded mapping. Create a QPSK demodulator having phase offset set to 0 .
