Secrecy Sum-Rate of Multi-User MISO Visible Light Communication Systems with Confidential Messages

This paper studies the information theoretic secrecy sum-rate for multi-user multiple-input single-output (MU-MISO) visible light communication (VLC) systems with confidential messages. The well-known Zero-Forcing (ZF) precoding method is employed to ensure confidentiality among legitimate users and, at the same time, to prevent eavesdropper(s) from obtaining any information. Different from rad...

Optimum Angle Diversity Receivers for Indoor Single User MIMO Visible Light Communication Systems

We propose a novel technique for single user MIMO-OFDM indoor visible light communication systems that optimizes the orientation angle of each photodetector in the receiver. Numerical results show that our technique outperforms conventional orientation method. OCIS codes: (060.4510) Optical communications; (060.2630) Frequency modulation

Enhanced Spatial Modulation of Indoor Visible Light Communication

In this study, we consider visible light communication in an indoor line-of-sight environment. It has been proved that among the multiple input multiple output (MIMO) techniques, spatial modulation (SM) performs better than repetition coding (RC) and spatial multiplexing (SMP). On the basis of a combination of SM and pulse amplitude modulation (PAM), here, we propose an enhanced SM algorithm to...
