Re: AD-FMCOMMS3-EBZ HIL example: QPSK modulation with raised cosine filter

Hi Arnd,

Thanks for posting the updated model. I too, am getting the switch between states, with a clear constellation being observed only briefly at regular intervals. I'm using a ZC706 with an AD-FMCOMMS3-EBZ board.

By the way, if I were to add a Phase / Frequency Offset block to the model, as described in the data verification step here: http://wiki.analog.com/resources/eval/user-guides/ad-fmcomms2-ebz/software/datafiles, how can I go about defining the initFcn simulink callback, so as to compute the PhaseOffset from the input data?

In the following code snippet, I assigned x and y to a constant value and I'd like to know how I can extract the appropriate values from the simulink model to feed as input to x and y:

x = 2;

y = 2;

[keypointx,I] = max(x);

[keypointy] = y(i);

degree = atan(keypointy/keypointx);

PhaseOffset=-degree/pi*180;

Regards,
