Dear all,
I'm doing some research on adaptive beamforming in OFDM systems.
But I have some questions in the simulation of co-channel interference(CCI).
(1) Normally, the signal model of received signal is :
which consist of signal part and interference part.
For the signal, we can generate it following the comm. system spec. (802.11a, 802.16)
But for the interference part(Zi), what kind of signal should we use? (the preambles, the modulation type,....)
(2) I have read several papers on the topic of beamforming, but I found that the simulation parameters (AoAs, CCI numbers, SIR, multipath gain,...) in the papers are all different.
So, I wonder if there's any formal spec. that is about the channel model of such environment (antenna array under CCI). (Like TGn channel models are used for 802.11n systems)
I'll be very appreciated for any opinion.
