论文摘要
接下来的高吞吐量卫星（HTS）系统运行Q/V频段网络网络（GWS）的馈线链接，需要应用某种形式的智能网关多样性（SGD），以确保它们满足苛刻的可用性目标。但是，关于SGD的大多数已发表研究通常都可以诉诸于对操作系统不现实的理想假设。为了更深入地评估实用SGD的性能，本文首次利用了40 GHz的六个测量位点（GWS）网络的多站点传播测量值。基于此，它研究了SGD在馈线可用性和GWS之间的开关数量方面的性能，并考虑到气候区域，开关处理延迟，GWS的群集以及Q/V频段上链接频率与上行链路频率的影响。沿着课程，强调了传播方面与SGD操作方面之间的相互作用。
Next generations of High Throughput Satellite (HTS) systems operating a Q/V band network of gateways (GWs) for the feeder link, need to apply some form of Smart Gateway Diversity (SGD) to ensure they meet the demanding availability targets. However, most of the published research on SGD usually resorts to ideal assumptions that are not realistic for an operational system. To evaluate in more depth the performance of practical SGD, this paper exploits for the first time multi-site propagation measurements for a network of six measurement sites (GWs) at 40 GHz. Based on this, it studies the performance of SGD in terms of feeder availability and number of switches between GWs taking into account the climatic region, the switching processing delay, the clustering of GWs, and the impact of downlink versus uplink frequency in Q/V band. Along the course, the interplay between propagation aspects and SGD operational aspects is highlighted.
