英文摘要	Owing to the logarithmic relation between the transmission rate and number of lasers of existing spatial modulation, the usage of spatial dimension is low. To address this challenge, a fully optical generalized spatial modulation (F-OGSM) system was proposed, in which different number of lasers was activated for transmitting information to achieve a linear relation between the transmission rate and number of lasers. Furthermore, to fully utilize all combinations of lasers, the channel norm maximization selection algorithm was used to select the active lasers, which effectively improved the system bit error rate(BER, RBE) performance. Moreover, the Monte Carlo simulation method was used to compare the performance of F-OGSM and existing optical space modulation schemes. When both the number of lasers and modulation order were 4, the transmission rate of the F-OGSM system increased by 1 bpcu compared with the generalized spatial pulse amplitude modulation. When RBE=1×10-3, the required signal-to-noise ratio of the F-OGSM system improved by 4 dB after using the laser selection algorithm. Conclusively, the proposed F-OGSM system exhibits a high-speed scheme that is particularly suitable for future atmospheric laser communications. © 2020, Chinese Lasers Press. All right reserved.
