The following example illustrates a simple example of a 3 bit per symbol QAM8
modulation with a particular constellation.
#3 // MyModulationFile
Iq
// Inner symbols
2.0, 0.0
0.0, -2.0
-2.0, 0.0
0.0, 2.0
// Outer symbols
3.0, 3.0
-3.0, 3.0
-3.0, -3.0
3.0, -3.0 // Final symbol
The above file does not include any unnecessary line in the header as it defines a non-
rotating, non-offset modulation so default values for these fields are used instead. The
resulting constellation after loading this file is shown as following:
