Hello,

I want to model a real GSM-R signal seen in a railway environment on Simulink.

Here is the model I have made so far.

Does it reflect a GSM-R signal ? Are there any missing blocks?

I would like to hear your opinion as an expert on modeling a real GSM-R signal seen in a railway environment.

I tried to simulate this model and I get this error:
