what MODCOD have been tested as working in the MathWorks example DVBS2XRegu​larModeBit​ErrorRateE​xample.mlx

I want to use the example to look at lower MODCOD like 16APSK, 32APSK and QPSK

Hey @Alden,

You can change the MODCOD by setting the corresponding PLSDecimalCode variable in the script. According to the example, "The example supports all modulation schemes from QPSK to 256APSK". You can edit it under the DVB-S2X Configuration, whose link within the example is below:

Sorry to be obtuse but this example at the bottom has differnt MODCOD % MODCOD 143 = 8PSK 23/36 which works in the example, but not in the origlinal code DVBS2XRegularModeBitErrorRateExample.mlx. :(

However the code you pointed me to DVBS2XWidebandModeBitErrorRateExample.mlx does much better as i can use MODCOD 174 32APSK with that one. (probably the noise setting is too high as defulat LOL)
