Hi guys, I am working on optical ofdm, its not much of a different from normal ofdm. I have a problem at the receiver side where my constellation shifts in phase.
So I did a very simple equalization, where the data before IFFT which will be in so call frequency domain, assume that as

Y/QUOTE].
So I did the channel estimation by takingand I will getwhich is the channel property. Then to get what I trasmitted at the receiver side, to compensate all the distortion, since H=Y/X, so to get backat the receiver, I didand I got back my exact constellation at the receiver.X=Y/H
Im not sure whether this is correct or no, please someone advice me on this. Thank you very much.
