I have a problem with the definition of SNR. We are working in a project regarding to WiMAX systems and we would like to know how SNR is defined in a WiMAX or in an OFDM system. In the WiMAX standard they didn't defined but they use it. And we know that they didn't use the SNRë/N0 equation. 1, How should we calculate SNR in our simulations? 2, We also use the charachteristics of several sector antennas, so do the manufacturers calculate the SNR values the way we should? I've read this post about the SNR: http://www.dsprelated.com/showmessage/34517/1.php but I can't download the papers linked in the post. ( my university s a limited accsess to the ieee site)
