Probabilistic shaping based spatial modulation for spectral-efficient visible light communication

1 min read · Sat, May 28 2022

Visible light communication (VLC) is a promising technology for 6th-generation (6G) networks because of its attractive feature such as a wide unlicensed spectrum. However, the modulation bandwidth of lens of commercially available light-emitting diode (LEDs), which are used in optical wireless data links, is limited. Therefore, in order to improve spectral-efficiency of VLC systems, a novel adaptive coded spatial modulation (SM) scheme with probabilistic shaping (PS) has been proposed. The authors also designed an algorithm to compute the capacity-achieving distribution of the proposed scheme
