Hi there,
I'm considering flat fading Rayleigh channel. My problem is that , after multiplying the signal by h and adding the AWGN it has this form r=h*tx+n and its obvious that this is a complex values. and to retrieve my data I estimated h at the receiver and divided the received data by it like this y=r/h and this also complex and I need a real values as an input to the logmap decoder..is it enough for me to just take the real of y or there some fancy steps I should consider.
Any suggestions are highly appreciated
