摘要

本文研究了一种基于宽带信号亚奈奎斯特采样的认知无线电信号处理体系结构。然后采用自适应数字滤波器对可能用于认知无线电的频段进行频谱扫描。特别地，本文研究了为应用信号处理方案量身定制的检测器，并考虑了由数字扫描滤波器引入的噪声相关性。

Spectrum sensing for cognitive radio architectures based on sub-Nyquist sampling schemes

This paper investigates a signal processing architecture for cognitive radio based on a sub-Nyquist sampling of the wideband signal. Then spectrum scanning is performed by applying an adaptive digital filter to scan the bands which might be used for cognitive radio. In particular, the paper studies detectors which are tailored for the applied signal processing scheme and which takes into account the noise correlation, introduced by the digital scanning filter.
