What does a constellation diagram show?

The constellation diagram shows all the possible symbols that can be transmitted by the system as a collection of points. In a frequency or phase modulated signal, the signal amplitude is constant, so the points lie on a circle around the origin.

What is constellation diagram and how is it used with PSK?

A constellation diagram is a diagram that shows how the information in a digital modulation scheme such as phase shift keying (PSK) is represented in a modulated carrier.

How many dots are in the BPSK constellation diagram?

To better understand this, recall that in BPSK there are only two constellation points, meaning that the entire I/Q plane is separated into just two sections with the decision boundary located on the Q-axis.
