It _is_ intended: http://dcis2009.unizar.es/FILES/CR2/p41.pdf So forget about my question :) Ralph. From: address@hidden [mailto:address@hidden On Behalf Of Ralph A. Schmid, dk5ras Hmm, now I see, there is an option "constellation rotation" in the modulator block. Maybe this is not an accident, but wanted behavior?! I will check this evening...
From: address@hidden [mailto:address@hidden] On Behalf Of Ralph A. Schmid, dk5ras Hi, With Rons help I got the DVB-T/T2 flowgraphs up and running. DVB-T works great, no issues at all, while DVB-T2 is somehow flaky in reception. When using a cheap DVB-x tester, the DVB-T2 constellation is phase shifted. I have no real world T2 signals to compare, but at least the tester shows normal constellation views when looking at S and T signals off the air. This is how things look: http://dk5ras.dyndns.org/tmp/DVB/ The flowgraphs are almost original, just adopted to the USRP B210, and I added channel slider... Any ideas what I could tweak? Ralph. |
