Buffer-Aided Max-Link Relaying for Free Space Optical Communication With Delay Constraints
IEEE Photonics Journal, 2022 In this paper, we introduce the concept of buffer-aided cooperative relaying for a free-space optical (FSO) communication system. The proposed FSO system consists of $K$ decode-and-forward(DF) relays, each equipped with a buffer of size $L$. The proposed
