Generalized space shift keying (GSSK) is a transmission scheme where only antenna indices are used to send information from the transmitter to a receiver. This paper investigates the best symbol set selection problem in GSSK multiple-input-multiple-output (MIMO) systems when the transmit antennas are correlated. Although multiple antennas can increase data rate and signal quality without increasing the bandwidth, spatial correlations among the antennas highly affect the performance of the system. The idea here is to maximize the inter-symbol Euclidean distance to obtain the best symbol set. Recently such an algorithm has been proposed for the visible light communication (VLC) systems. This paper adopts this VLC algorithm for radio frequency (RF) communication systems. The results show that the proposed symbol set design can provide several dBs of gain in the symbol error rate (SER) performance over randomly selected symbol sets in GSSK systems.Sponsors
