dc.description.abstractVisible Light Communication (VLC) systems using an array of LEDs as a transmitter and a digital camera as a receiver can provide reliable communication. Such systems can employ various modulation formats that include the generalized space shift keying (GSSK), where only the indices of the LEDs are used to send information. This paper investigates the modeling of GSSK VLC systems under different atmospheric conditions as well as for underwater channels, and investigates the problem of selecting the best set of modulation symbols. The behavior of such systems is modeled using the point spread function, and the inter-symbol Euclidean distance is maximized to obtain the best symbol set. The paper adopts the recently proposed symbol set selection algorithm from the literature exploiting the clustering property of GSSK VLC systems. The results show that the symbol set design algorithm can provide several dBs of gain in the symbol error rate (SER) performance over randomly selected symbol sets in GSSK systems under various atmospheric conditions as well as for underwater channels.
