The constellation diagram is a graphic representation of the digital symbols
received over a period of time. There are different types of constellation
diagrams according to the modulation type.
In the case of an ideal transmission channel without noise or interference, all
symbols are recognized by the demodulator without errors. In this case, they
are represented in the constellation diagram as well defined points hitting in the
same area forming a very concentrated dot.
Noise and interferences cause the demodulator to not always read the symbols
correctly. In this case hits are dispersed and create different forms which can
visually determine the type of problem in the signal.
Each type of modulation is represented differently. A 16-QAM signal is shown on
screen by a diagram of a total of 16 different zones and a 64-QAM signal is
represented by a diagram of 64 different zones and so on.
The constellation diagram shows in different colours the density of hits and
includes features to zoom, move and delete the display on screen.
The constellation is available to all digital signals, both terrestrial and satellite.
