摘要:In this paper, direct-code generalized space shift keying (DC-SSK) has been studied for indoor visible light communication (VLC) system with the purpose to improve the system transmission rate. Symbol error rate (SER) of the DC-SSK scheme in VLC system has been derived based on the maximal likelihood (ML) detection and low complexity power allocation scheme has been further presented to enhance the system performance over high correlation optical channel. Simulation results and theoretical analysis show the proposed DC-SSK scheme with low complexity power allocation can achieve better spectral efficiency and SER performance of VLC system. Effect of the different semiangles of the LEDs at half-power on the system performance has also been analyzed.
