How to plot the 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.

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.

What does a constellation plot show?

A constellation plot (or diagram) is one of the most widely used means of presenting a signal modulated by a digital scheme - Quadrature Amplitude Modulation (Figure 1), Phase-shift keying, Amplitude-shift keying (Figure 2), etc.

How to plot QAM in Matlab?

QAM Symbol Ordering

Plot QAM constellations for Gray, binary, and custom symbol mappings. Set the modulation order, and create a data sequence that includes a complete set of symbols for the modulation scheme. M = 16; d = [0:M-1]; Modulate the data, and plot its constellation.
