Abstract

Abstract: The propagation characteristic of over-sea buoy communication based on L-band is analyzed. On the basis of dynamic ocean wave curve simulation，the channel impulse response model is formulated combined with ray tracing method and numerical analysis，which can be applied to various sea states. The cumulative probability distribution curve of channel reflection point numbers and channel power is derived. Numerical simulation has been done according to buoy-satellite link and buoy-vessel link under different sea states，which is compared with the simulation results of traditional 2-ray model and AWGN model. The study results indicate that the sea state and the incident angle significantly influence link BER performance，while traditional 2-ray model is insufficient to describe channel propagation characteristic. The study is of great importance in practical buoy communication link budget.

摘要： 分析了基于L波段浮标海上通信的链路传输损耗特性，以模拟动态海浪曲线为基础，结合射线追踪与数值分析思想，建立了适用于不同海况等级的信道冲激响应模型，给出了信道反射点数目与功率的累积分布概率曲线，最后以浮标-卫星与浮标-舰船两种链路为例，仿真得到了不同海况下的误码率曲线，并与传统两径信道与高斯白噪声信道结果进行对比。分析结果表明，海况恶劣程度与入射波仰角大小对链路误码率影响显著，传统两径模型不足以描述其传播特性，该研究对实际浮标通信链路预算具有重要意义。
