I have a M file with the codes of my channel transfer function. My transceiver model however is built in Simulink. Is there a way to simulate my transceiver with my transfer function without any S-function programming? I'm close to my due date and this instruction was given to me last minute by my instructor. Please advise. Thank you.

Hello, I'm trying to learn how to use Simulink and I'm trying to modify the dvb-t demo. I don't understand why the Ts of the source is computed as Ts=0.000224*2176/9072/188 . For sure I know that it depends from the mode (2k) and the mapping used (64-QAM), but I can't understand why is computed in this way. Could you make an example (i.e. mode 8K,16-QAM).
