摘要

本文全面研究了采用子载波相移键控(SC-PSK)信令的涡轮编码自由空间光学(FSO)系统的性能。我们得到了系统的误码率(BER)和信道容量在伽玛-伽玛强湍流信道上在非编码和涡轮编码情况下的理论界限。我们定量地表明，强湍流对误码率和信道容量有很大的影响。在涡轮编码系统中，在强湍流状态下可以实现约4 dB的编码增益和5%的信道容量增加。

Performance bounds for Turbo-coded SC-PSK/FSO communications over strong turbulence channels

This paper comprehensively investigates the performance of the Turbo-coded free-space optical (FSO) system using subcarrier phase shift keying (SC-PSK) signaling. We obtain theoretical bounds for the system's bit-error rate (BER) and channel capacity over the gamma-gamma strong turbulence channels in both uncoded and Turbo-coded cases. We quantitatively show that the BER and channel capacity are considerably affected by the strong turbulence. In Turbo-coded systems, a coding gain of about 4 dB and 5% channel capacity increase can be achieved in the strong turbulence regime.
