OFDM frequency spectrum

Hello guys,

I don't know a lot about matlab simulink, so I was wondering if someone can
help me so I can figure out the spectrum of an ofdm. I want the complex data
out from the transmitter to be analogized separately- I mean the real and
imaginary signals each one alone- then digitized by a sampling rate that is
twice the value of the digital transmitted signal.

Thanks in advance,

i think you are trying to upsample the transmitted signal by a factor of
2 ? there is nothing as 'analogization' in simulink or MATLAB. Thats all
sampled though you can increase the sampling rate to a very higher value
to simulate an analog signal. To increase the sampling rate you need
some sort of interpolation filter.
