Thank you so much for all the work in the BER, i tested both of the flowgraphs and they are very accurate regarding the BER measurements, i have a couple of questions if you don´t mind:
1- In the latest flowgraph you sent (my-ber-test.grc from Jan 25th) how do you change the modulations in the chunks to symbols block, in the flowgraph you sent me the flowgraph table was fixed with the values of "-1, 1", what line of commands should be place there to switch to other modulations?
2- The BER measurements you sent me seem so accurate, I wonder if you could take a look at the flowgraph i sent you (my_ber_simulation_LFA.grc), what i did there was connecting a QT GUI Chooser to the functions i thougth would change the constellation selected, do you have any ideas why my change is not working, when i change in the QT GUI Chooser?, i would appreciate your help regarding this.
3- Attached is a flowgraph i have devloped for doing modulations up to 64 QAM, please take a look at it, and if you have any ideas on how i would make a good BER measurement of higher modulations (32 -QAM and 64-QAM) please let me know. To select the modulatios, the easiest way is to define in the default value of the QT GUI chooser the value of 3 (for 32-QAM) and the value of 4 (for 64 QAM).
Once again thanks a lot for all the help.
