Abstract
Conference Title: 2018 IEEE Wireless Communications and Networking Conference (WCNC) Conference Start Date: 2018, April 15 Conference End Date: 2018, April 18 Conference Location: Barcelona, Spain In this paper, we propose the new design of pyramidal angle diversity receiver with a help of mirror in indoor multiple-input multiple output (MIMO) visible light communication (VLC) systems. Embedding the mirror around the photodetector (PD) planes can help compensate for the high correlation of MIMO-VLC channel matrix. The channel gain of newly proposed receiver structure is derived based on the geometry of transmitter/receiver and azimuth/elevation angles of PD and mirror. From the selected numerical results, we see that the proposed receiver structure can further improve the channel capacity of MIMO-VLC systems when the receiver is located in the region where the channel correlation can dominantly degrade the channel capacity.
