The following is a more complex example:
#3
Offset, no
Rotation, 10.0
RotMODE, cont
iq
1.0, 0.0
2.0, 0.0
0.0 ,1.0
0.0, 2.0
-1.0, 0.0
-2.0, 0.0
0.0, -1.0
0.0 ,-2.0
The above file is composed of a header with relevant information. In this particular case,
the file contains 8 (2
3
) IQ pairs. The ‘IQ’ characters indicate the starting point for the
symbol location list composed by 8 lines with I/Q pairs separated by commas. I and Q
will not be delayed (‘Offset, no’) and constellation will rotate by 10.0 degrees (‘Rotation,
10.0’) in a continuous fashion (‘RotMODE, cont’). In fact, the ‘Offset’ and ‘RotMode’
fields could be removed without any effect on the final signal as these fields take the
default values. The resulting constellation after loading this file is shown as following:
