摘要：
In this letter, we propose the optimal constellation designs of the single-mode and dual-mode generalized spatial modulation (GSM) in terms of the average optical power for indoor visible light communication systems. At receiver, an ordered-block maximum likelihood detection is performed to balance the tradeoff between the performance and the computational complexity. Our simulation results show that the dual-mode scheme outperforms SM and single-mode GSM by about 4 and 2 dB, respectively, for 5 bit/s/Hz in terms of bit error rate.
