摘要

波浪引起的波束漂移会降低通信性能，从而导致水气 OWC 的误码率 (BER) 和丢包率 (PLR) 偏高。我们提出了一种实时波束跟踪系统，利用图像预处理算法和基于 MobileNetV2 的模型来减轻水气 OWC 中的波浪诱导效应，并进行了实验演示。该跟踪系统经过优化，在跟踪和通信性能方面与基于 ResNet 的跟踪系统进行了比较。在非跟踪情况下，PLR 明显更高，数值超过 20%。在数据传输速率为 800 Mbit/s、波浪平均坡度变化率 (ASCR) 为 28 度/秒的情况下，基于 MobileNetV2 的跟踪方法实现了 1.3 米空中路径的零丢包链路。

Beam Tracking Aided by Complexity-Reduced MobileNetV2 for Water-Air OWC With Waves

Wave-induced beam wander degrades communication performance, which causes a high bit error rate (BER) and packet loss rate (PLR) in water-air OWC. We propose and experimentally demonstrate a real-time beam tracking system utilizing an image pre-processing algorithm and a MobileNetV2-based model to mitigate wave-induced effects in water-air OWC. The tracking system is optimized and compared with the ResNet-based tracking system in terms of tracking and communication performance. For non-tracking cases, the PLR is significantly higher, with values exceeding 20%. With a 1.3-m air path, a zero-packet-loss link is realized by the MobileNetV2-based tracking method at a data rate of 800 Mbit/s and a wave average slope changing rate (ASCR) of 28 deg/sec.
