What is constellation diagram of PSK?

A constellation diagram is a representation of a signal modulated by a digital modulation scheme such as quadrature amplitude modulation or phase-shift keying. It displays the signal as a two-dimensional xy-plane scatter diagram in the complex plane at symbol sampling instants.

How many points are there in 16 PSK constellation diagram?

Create 16-PSK Constellation Diagram

This example shows how to plot a PSK constellation having 16 points. Set the parameters for 16-PSK modulation with no phase offset and binary symbol mapping.

Why do we use constellation diagram?

The constellation diagram is useful because it displays both the ideal (reference) signal and the actual measured signal on the same plot. The ideal signal locations of a constellation diagram are pre-defined generically depending on the modulation format chosen.
