海上太赫兹通信系统设计

Design of marine terahertz communication system

摘要:

海面舰艇间及舰艇与飞行器间存在大容量、抗干扰安全可靠传输需求，太赫兹频段频率高，带宽大，是大容量传输和抗干扰通信的优良手段。针对海上太赫兹通信的特点，分析了我国海面上太赫兹波受水汽衰减的影响；在链路预算与传播可靠度计算的基础上，设计了一套海上太赫兹通信系统，并经过150 m水上实测。在误码率满足2×10^-8的情况下，速率可达520 Mbps，验证了系统的可行性。

Abstract:

The demand for high-capacity, anti-interference, safe and reliable transmission between ships on the sea and between ships and aircraft is becoming urgent. Terahertz band has a high frequency band and large bandwidth, making it an excellent means of high-capacity transmission and anti-interference communication. Based on the characteristics of marine terahertz communication, the influence of water vapor attenuation on terahertz wave on the sea surface in China is analyzed firstly. Then, based on the link budget and propagation reliability calculation, a marine terahertz communication system is designed. After being tested on a 150 m river, the system's feasibility is verified by achieving a speed of 520 Mbps with an bit error rate of 2×10^-8.
