声学调制解调器可以进行远距离水下通信，但相对昂贵，数据速率有限。已经开发了低成本的调制解调器来解决商业产品的高成本问题，但数据速率仍然有限。对于需要短距离(<；50米)、高速通信的水下机器人应用，存在不同的通信解决方案；光纤。然而，目前还没有可用的低成本、开放源码的光纤调制解调器来满足社区的需求。在本文中，我们讨论了我们在开发这样的调制解调器方面的进展，并在陆地上实验验证了我们的硬件。我们演示了传输距离达50米(陆地)，最坏情况下的信噪比为18.8分贝(直接视线)。
Acoustic modems enable long-range underwater communication, but are relatively expensive with limited data rates. Low-cost modems have been developed to address the high cost of commercial products, but data rates are still limited. For underwater robotics applications with the need for short-range (<50 m), high-speed communication, there exists a different communication solution; optical. However, there currently is no available low-cost, open-source optical modem to address the needs of the community. In this paper, we discuss our progress towards development of such a modem and experimentally verify our hardware on land. We demonstrate a transmission distance up to 50 m (on land) with a worst-case signal-to-noise ratio of 18.8 db (direct line-of-sight).
