基于USRP-E110的频谱感知

Spectrum Sensing with USRP-E110

Luis Sanabria-Russo, Jaume Barcelo, Albert Domingo, Boris Bellalta

摘要:

频谱感知是实现未来无线服务(如SuperWiFi)的关键主题之一。这一新的无线提案旨在利用电视频道从模拟到数字的过渡所产生的空闲频谱进行无线数据传输(UHF电视空白)。与IEEE 802.11标准相比,其优点包括更好的建筑物穿透力和更长的距离。然而,可用频谱的有效使用受到严格的监管,禁止未经许可的用户干扰现任者(如无线麦克风)。认知无线电(CR)和动态频谱分配是解决这一问题的有效方法。这些技术包括TV-UHF频段的频率扫描,以检测可用于SuperWiFi传输的空白频段。在本文中,我们开发并实现了GNURAdio在Ettus USRP-E110中的算法,以构建一个独立的空白检测器,可以通过IP网络从集中位置进行咨询。

英文摘要:

Spectrum sensing is one of the key topics towards the implementation of future wireless services like SuperWiFi. This new wireless proposal aims at using the freed spectrum resulting from the analog-to-digital transition of TV channels for wireless data transmission (UHF TV White Spaces). The benefits range from better building penetration to longer distances when compared to the set of IEEE 802.11 standards. Nevertheless, the effective use of the available spectrum is subject to strict regulation that prohibits unlicensed users to interfere with incumbents (like wireless microphones). Cognitive Radios (CR) and dynamic spectrum allocation are suggested to cope with this problem. These techniques consist on frequency sweeps of the TV-UHF band to detect White Spaces that could be used for SuperWiFi transmissions. In this paper we develop and implement algorithms from GNURadio in the Ettus USRP-E110 to build a standalone White Spaces detector that can be consulted from a centralized location via IP networks.
