How to observe QAM singals in timedomain in Simulink?
Posted:

I am trying to build up an OFMD transmitter by using Simulink. The chosen modulation scheme is 64QAM. I am wondering how to observe the QAM signals in timedomain.
My simulink model consists of the following key blocks: Random integer generator, QAM modulator, S/P converter, IFFT block, Cyclic prefix block, buffer and Spectrum scope.
After the IFFT algorithm, the frequencydomain QAM signals in converted to timedomian signals. How to observe the QAM signals in timedomain?
Many thanks if someone can give some guidance./Lei
