hye there..i need help in doing simple ofdm in simulink. this model i refered from demo
hiperlan2. the thing is, i can run the simulation with no errors warning. but in the end, my
probability of error is still around 0.5 out of 1. anyone knows?
here's my block sets of ofdm.

hi,

I have had the same problem before. The reason is when you try to transmit the signal with real
and image (Ex 4QAM), there is somewhere that the phase is completely false or vice versa, the
real part of your signal after matched filter has the opposite sign (from minus to plus or
v.v). 
I think you should look at your code again and check if everything is working properly.

Hope it helps.

Best Regard,
