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.

What is a constellation point?

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 many output phases are possible in 8-PSK?

In 8-PSK there are eight possible phases which the carrier can have at a given time, as shown at right on the characteristic constellation for this modulation type.

How are constellations used in PSK?

In PSK, the constellation points chosen are usually positioned with uniform angular spacing around a circle. This gives maximum phase-separation between adjacent points and thus the best immunity to corruption. They are positioned on a circle so that they can all be transmitted with the same energy.
