I am exploring the BER measurements in GNU Radio for different modulations (I know Error Rate is deprecated) but i tried the example under the digital folder for BER measurement and I understood all the flowgraph.
After this i wanted to change the modulation in the QT GUI so i added a QT Gui Chooser as seen in the flowgraph below:
Attached is the flowgraph for reference.
When i add this i expected that the Constellation would change accordingly, but it does not when i choose a different constellation with the chooser, for instance if the default value in the chooser is QPSK it shows at the beginning:
But If i switch in the same running time to 8-PSKn it shows:
Which is not an 8-PSK modulation scheme.
I would appreciate some help,. regarding what i am doing wrong for choosing a Modulation through the QT GUI.
Thanks in advance.
