Abstract :
We describe a semi-blind algorithm for smart antennas that, in addition to structural signal properties, utilises user identifiers that are available in existing cellular systems. Assuming two co-channel users in a GSM-like TDMA system and a Rayleigh fading channel with finite angular spread, we obtained a BER<10-3 with only 2-3 antennas. We show the performance of the algorithm in several different simulation scenarios also including array imperfections and angularly non-separable sources
