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.
