基于Q/V频段多站测量的实用智能网关分集评估
Assessment of Practical Smart Gateway Diversity Based on Multi-Site Measurements in Q/V band
摘要：
下一代高吞吐量卫星（HTS）系统运行用于馈线链路的Q/V波段网关（GW）网络，需要应用某种形式的智能网关分集（SGD），以确保它们满足苛刻的可用性目标。然而，大多数已发表的关于SGD的研究通常采用理想的假设，这些假设对于操作系统来说是不现实的。为了更深入地评估实际SGD的性能，本文首次利用了40 GHz的6个测量站点（GW）的网络的多站点传播测量。在此基础上，它研究了SGD的性能在馈线可用性和GW之间的开关数量考虑到气候区域，切换处理延迟，集群的GW，和下行链路与上行链路的频率在Q/V波段的影响。沿着课程，传播方面和SGD运营方面之间的相互作用是突出的。
英文摘要：
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.
