Abstract

Multiple-input-multiple-output (MIMO) technique for visible light communications (VLC) facilitates higher data rate thanks to parallel data transmission. However, full channel-state information (CSI) is a requirement in a MIMO system at all times for successful data recovery, which is a major challenging factor in mobility and shadowing scenarios. In this paper we introduce a novel approach for a self-correcting MIMO system's CSI that enables robustness against channel blocking and overcomes the reduced rank of the CSI matrix thanks to the self-estimation of the MIMO receiver position. This approach is designed to provide seamless MIMO VLC operation. The paper presents the theoretical modelling and numerical evaluation. We show that the system can achieve data recovery for all channels even though one channel (or more) loses the pilot signal, which are used for determining the CSI.
