Abstract

In this paper, we investigate Multiple-input Multiple-output (MIMO) techniques implemented on the PHY layer of IEEE802.11× modems deployed for metro applications in tunnels. We analyze the performance in terms of bit error rate (BER) of three well-known quantized precoders: LTE, max-d_min and P-OSM, in coded MIMO systems in subway tunnels in presence of impulsive noise. We consider measured channel models and an impulsive noise distribution obtained thanks to measurements in tunnels and in railways environments. Different levels of correlation in the tunnel and also the channel estimation quality are taken into consideration.
