We compare various space shift keying multiple input multiple output (SSK-MIMO) techniques such as generalized space shift keying (GSSK), hamming code aided space shift keying (HSSK) and variable generalized space shift keying (VGSSK) for visible light communication (VLC) system. In addition, we analyze the bit error rate (BER) performance of these schemes for channels with different correlations. The BER expressions of these schemes are analytically approximated and used for the performance comparison. The suitability of VGSSK-MIMO for VLC is justified by its performance gain obtained over the other better performing SSK-MIMO systems. From the simulations, it is observed that the performance gain of 1 dB is achievable steadily under both high and less correlated channels for 3 bit/s/Hz by GSSK over HSSK.
