Propagation characteristics of over-sea buoy communication channel at L-band
摘要
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.关键词
