Physical Layer Security for Multi-User MIMO Visible Light Communication Systems with Generalized Space Shift Keying Authors:Su, Nugman; Panayırcı, Erdal; Koca, Mutlu; Yeşilkaya, Anıl; Poor, Harold Vincent; Haas, Harald
Publisher and Date:(Institute of Electrical and Electronics Engineers Inc., 2021)We consider the physical layer security (PLS) of multi-user (MU) multiple-input-multiple-output visible light communication (VLC) systems with an eavesdropper (Eve) and propose a novel spatial constellation design technique based on generalized space shift keying (MU-GSSK-SCD). The received signals of the legitimate users are optimized jointly, such that their bit error ratios (BERs) are minimized and Eve's BER is significantly degraded. The emission power of randomly selected light-emitting diodes ...
Spatial Constellation Design Based Generalized Space Shift Keying for Physical Layer Security of Multi-User MIMO Communication Systems Authors:Su, Nugman; Panayırcı, Erdal; Koca, Mutlu; Poor, H. Vincent
Publisher and Date:(Institute of Electrical and Electronics Engineers Inc., 2021)We propose a novel spatial constellation design (SCD) method with generalized space shift keying (GSSK-SCD) signaling for physical layer security (PLS) in multi-user (MU) multiple-input multiple-output (MIMO) communication systems. In GSSK-SCD, the received spatial constellations are optimized through a novel precoding scheme, which minimizes the BERs at legitimate users and significantly worsens eavesdroppers’ BER. In addition to extensive BER simulations, we also provide analytical expressions ...
