由于过去几十年来的重大技术进步，水下应用的普及程度一直在增长。然而，从空中节点到水下节点的直接通信仍然具有挑战性，因为任何已知的信号都不能在空气和水介质中良好地传播。光声能量转移是一种很有前途的机制，使这种跨介质通信。尽管光声机制在医学成像中的使用相当普遍，但在构建通信协议栈方面取得的进展很少。大多数研究仅集中在表征通道以及将激光和声学信号相关联。很少有人注意开发合适的调制和解调方案。本文填补了这一技术空白，提出了一种基于峰值检测技术的OOK调制方案。我们通过仿真和实验室实验验证了我们提出的方案的有效性。
The popularity of underwater applications has been growing due to the major technological advances in the last few decades. Yet, direct communication from an airborne node to an underwater node remains challenging due to the inability of any known signal which propagates well in both the air and water mediums. Photoacoustic energy transfer is a promising mechanism for enabling such cross-medium communication. Although the use of the photoacoustic mechanism is quite common in medical imaging, little progress has been made on building the communication protocol stack. Most research studies have only focused on characterizing the channel and relating the laser and acoustic signals. Little attention has been given to developing suitable modulation and demodulation schemes. This paper fills such a technical gap and proposes a novel OOK modulation scheme using peak detection technique. We validate the effectiveness of our proposed scheme through simulation and lab experiments.
