Abstract

The present study examined and simulated the coding or no coding performance for different configurations of multi-input, multioutput underwater wireless optical communication systems. MIMO diversity and channel coding were used to reduce the power transmitter, assuming lognormal distribution random for weak ocean turbulence. The simulation tested for a link range of 30 m in low ocean turbulence and 500 Mbps on–off-keying was also presented using Monte-Carlo. The results showed improvement in power transmitted (gain) for 2x5 compared to Uncoded SISO, which was about 33.60db using the concatenated code. So that the underwater wireless optical communications (UWOC) even now will also be significantly impacted by the Internet of Underwater Things (IoUT) and ultimate mobile technologies five generation communication systems because of their extraordinarily high demand for data safety, bit rate, energy consumption, so it is used in combined data transfer between underwater communication devices. The UWOC system based on coded MIMO may successfully be used in IoUT due to its high robustness and power qualification.

利用编码多输入多输出分集实现物联网水下无线光通信

本研究考察并模拟了不同配置的多输入多输出水下无线光通信系统的编码或无编码性能。假设弱海洋湍流为对数正态分布随机，使用多输入多输出分集和信道编码来降低发射功率。还使用 Monte-Carlo 对低海洋湍流中 30 米的链路范围和 500 Mbps 的开关密钥进行了模拟测试。结果表明，与未编码 SISO 相比，2x5 的传输功率（增益）有所提高，使用串联代码的传输功率（增益）约为 33.60db。因此，水下无线光通信（UWOC）即使现在也将受到水下物联网（IoUT）和终极移动技术五代通信系统的重大影响，因为它们对数据安全、比特率、能耗的要求特别高，所以它被用于水下通信设备之间的组合数据传输。基于编码多输入多输出（MIMO）的 UWOC 系统具有很高的鲁棒性和功率合格性，可成功应用于 IoUT。
