监视雷达和辅助Wi-Fi网络之间的频谱共享
Spectrum Sharing Between A Surveillance Radar and Secondary Wi-Fi Networks
摘要：
在3-GHz频带中与陆地（例如空中交通管制）和船载雷达在空间-时间上共享频谱的未授权网络之间的共存吸引了显著的兴趣。类似于每个主-辅共存场景，从未许可设备到主接收机的干扰必须在可接受的范围内。在这项工作中，我们制定了一个脉冲，搜索雷达（主要）和802.11 WLAN作为次要的频谱共享问题。我们计算这样的搜索雷达的保护区域a）一个单一的二级用户（最初）以及b）多个二级用户的随机空间分布。此外，我们还分析了从雷达的传输到WiFi设备的干扰，以估计对可实现的WLAN吞吐量的影响，作为到主雷达的距离的函数。
英文摘要：
Co-existence between unlicensed networks that share spectrum spatio-temporally with terrestrial (e.g. Air Traffic Control) and shipborne radars in 3-GHz band is attracting significant interest. Similar to every primary-secondary coexistence scenario, interference from unlicensed devices to a primary receiver must be within acceptable bounds. In this work, we formulate the spectrum sharing problem between a pulsed, search radar (primary) and 802.11 WLAN as the secondary. We compute the protection region for such a search radar for a) a single secondary user (initially) as well as b) a random spatial distribution of multiple secondary users. Furthermore, we also analyze the interference to the WiFi devices from the radar's transmissions to estimate the impact on achievable WLAN throughput as a function of distance to the primary radar.
