OFDM simulation without FFT on simulink

simulink fft

Hi,

first, I'm not english so I'm sorry for my poor language.

My project is to make a model of baseband OFDM transmission without FFT/IFFT on simulink.

So on the first side I take a bernoulli binary and Rectangular 4-QAM to build complex symbols and on the second side I make my 3 complex sine with frequencies [-fo 0 fo]. Then I multiply sines by my vector of 3 symbols.

Then I multiply conjugate of my sines by the result of the last operation and I sample it.

But my problem is that this model don't work...

could Anyone help me pliz ?

Thanks you

Hi friend,

please explain more as i can not understand you also i see that you did not implement the above words in the figure ( if i am false please correct me)

hi aya2002
can u plz guide me to the track that how shuld i start my working as i m doing a project on CREATING AN OFDM MODEL IN MATLAB AND THEN IMPLEMENT IT ON FPGA.
