I-Q Signal for DAB

Hi everyone,

I am just trying to simulate a FM receiving chain with ADS. That works so far, but now I want to implement an interferer, an DAB signal. Therefore I somehow should get data of such a signal, the I-Q data or the combined signal, which is sent out in the real world. I need that as an ASCII-file, a .txt file or something like that. So... could anyone please help me? Is there a MATLAB script or Simulink simulation that creates such a signal? Thanks in advcance for your answers and your help. :)
