Abstract

In indoor visible light communications (VLC) systems, line of sight (LoS) blockage severely impairs the received power of users. To address this issue, in this paper, a paradigm of indoor space shift keying (SSK) VLC system aided by mirror array is investigated. Firstly, the mirror array reflects the light signal received from LEDs to the user’s photo-detector (PD) by the virtue of mirror reflection characteristics. And then, a method of power focusing is presented by adjusting the angle of the mirror according to the locations of LEDs and PDs. Additionally, the synchronous issue is analyzed theoretically to address the multipath effects. Furthermore, an orthogonal matching pursuit (OMP) detection algorithm aided by singular value decomposition (SVD) is proposed for the considered system. Finally, simulations are presented to verify the effectiveness of the proposed mirror array aided indoor SSK-VLC system.
