Demodulator block in comm.OFDMDemodulator doesn't return real values?

I have used the following block diagram to try and demonstrate that OFDM can mitigate the effects of multipath and intersymbol interference. My input is an impulse train with positive impulses of +1 and 0.
The OFDM Demodulator block is supposed to return values that are either 0 or 1 - but it is returning complex values that were obtained while Modulating. Why is this happening?
I have enclosed the input signal, modulated signal and demodulated signal. What am I doing wrong?
input signal:
- modulated signal: *
- output signal: *

Can you share this simulink file with me ? I really need this one, I am trying to assemble OFDM modulator from last week, but it gives me various error. Could you help me with this? Can you send this .slx file to my mail ? - nileshjadav991@gmail.com
