摘要：In this paper, we propose an incremental hybrid decode-amplify-forward (IHDAF) cooperative scheme based free space optical (FSO) communication system to resist the performance degradation caused by path loss, atmospheric turbulence, and pointing errors. The IHDAF cooperative FSO system can choose direct transmission, decode-and-forward (DF) and amplify-and-forward (AF) relaying protocols flexibly according to the instantaneous channel state information (CSI) and signal-to-noise ratio (SNR). The outage probability analysis of the IHDAF cooperative FSO system is also presented in the weak turbulence channel with pointing errors. Numerical results show that the proposed IHDAF cooperative FSO system improves the system performance compared with the other conventional cooperative FSO systems. Moreover, we also study the effects of the power allocation and the relay position on the system performance of the proposed IHDAF cooperative FSO system. © 2018 Global IT Research Institute (GiRI).
