N-dim Simulink Simulation (OFDM)

Hi,

first off all, sorry for the bad english. Ich have the following problem. I want to creat a OFDM Simulation with Simulink and I don't know who I can modulate N (for example 100) QPSKs parallel. I don't want to build in the QPSK block 100 times :)

Is there a possibility to make this in an easy way?

Thanks for help!
