摘要

自由空间光通信（FSO）由于其高带宽和易于部署而成为一个热门的研究领域。然而，远距离无线光通信系统的性能经常受到大气湍流的影响。为了应对这一挑战，本文提出了一种集成了自动重复请求（ARQ）、前向纠错（FEC）、交错和自适应调制（AM）的跨层设计。为了评估该系统的性能，我们进行了一个11公里的远程波束传播实验，以收集信道衰落的数据。基于实验采集的数据和马尔可夫链理论，建立了ARQ的有限排队系统模型，推导了所设计的通信系统的吞吐量、帧延迟和能量效率。仿真结果表明，该系统能有效地提高远距离FSO通信的稳定性。

Integrated FEC, Interleaving, ARQ, and Adaptive Modulation for Long-Distance Maritime Communication Systems: Design and Analysis

Free-space optical communication (FSO) has been a popular research area due to its high bandwidth and ease of deployment. However, the performance of long-distance FSO system is often compromised by atmospheric turbulence. To address this challenge, this paper proposes a cross-layer design that integrates automatic repeat request (ARQ), forward error correction (FEC), interleaving, and adaptive modulation (AM). To evaluate the performance of this system, we conducted an 11 km long-distance beam propagation experiment to collect data on channel fading. Based on the experimental collected data and Markov chain theory, a finite queuing system model for ARQ is established, and the throughput, frame delay and energy efficiency of the designed communication system are derived. The numerical results indicate that the proposed system can effectively improve the stability of long-distance FSO communication.
