摘要：In our paper, we propose an indoor cooperative incremental hybrid decode-amplify-forward (IHDAF) protocol based spatial modulation (SM) visible light communication (VLC) system to resist the channel propagation fading and improve the system performance, which flexibly selects the direct transmission or the corresponding cooperative relaying protocol according to the instantaneous channel signal-to-noise ratio (SNR). The system model of the proposed cooperative IHDAF protocol based SM VLC system and the detailed signal processing algorithm are presented. Numerical results show the significant performance improvement of the proposed scheme compared with the conventional amplify-and-forward (AF) and decode-and-forward (DF) based SM VLC systems. Furthermore, the power allocation scheme of the proposed cooperative IHDAF SM VLC system is also investigated. © 2018 IEEE.
