In this paper, we propose a MIMO-OFDM indoor VLC system with orthogonal circulant matrix transform (OCT) precoding and angular receivers to significantly improve the achievable aggregate capacity of equivalent parallel channels. Compared with the conventional MIMO-OFDM based VLC systems, the data streams of LED transmitters in our proposed system are linearly pre-processed with the OCT precoding scheme...
Multiple input multiple output (MIMO) technology appears attractive for indoor visible light communication (VLC) systems as multiple light-emitting diodes (LED) sources are typically deployed for indoor environment. Most of current indoor MIMO VLC systems utilize single user terminal scenario to investigate the performance of the system. However, typical arrangement of a practical indoor environment...
