摘要

频谱感知是整个认知无线电操作所依赖的任务。在本文中，我们提出了一种基于从非均匀压缩多共集样本中获得的多频带信号的频谱估计的频谱传感技术。结果表明，本文提出的频谱传感方法使用较少的数据样本就能获得准确的结果。我们详细讨论了假检测对从非均匀多共集样本中获得的重构信号质量的影响。

Spectrum sensing for cognitive radio using multicoset sampling

Spectrum sensing is the very task upon which the entire operation of Cognitive Radio rests. In this paper, we propose a spectrum sensing technique based on the estimates of the spectrum of a multiband signal obtained from its non-uniform compressed multicoset samples. We show that our proposed spectrum sensing method provides accurate results using less data samples. We discuss in detail the effect of false detections on the quality of the reconstructed signal obtained from non-uniform multicoset samples.
