quadrature lo in simulink

Hi,I am facing problem when implementing single sideband,double sideband,and unmodulated carrier as shown below in matlab simulink.
-anyone knows what is Ilo and Qlo?What should i put in simulink model?
-wat is the "data" means?Do i need to supply data to the raised cosine filter?
-the mixer can use product block to represent them?
-the "1" and"0" are just normal constant?
Thanks and i really appreciate if anyone can help or give me some advices.

Ilo and Qlo are the quadrature LO signal, just give some orthorgonal signal (sin and cos) at the frequency you want.


-wat is the "data" means?Do i need to supply data to the raised cosine filter?
Yes, that's what do you want to transfer

-the mixer can use product block to represent them?

Yes,

-the "1" and"0" are just normal constant?

Yes.

Thanks and i really appreciate if anyone can help or give me some advices.
