Hi Antonio, I tried to open your GRC file. This must have been with a pretty old version of GNU Radio (which version are you using?). I strongly recommend getting a newer version of GNU Radio, because especially the OFDM code has improved a lot. By the way, a BER of about ~0.5 means that as many bits are right as there are wrong bits, which means that you get absolutely no information through (if there were more wrong than right bits, you could just toggle the bits and get more information); this means that the input and output streams are not related, or have an offset relative to each other that doesn't get corrected; increase the BER window size (you don't need the delay if you've got a bigger window).
