摘要

宽带频谱感知是认知无线电网络中的一个基本问题。针对基于调制宽带变换器(MWC)的亚奈奎斯特速率认知无线电系统,提出了一种由粗支持恢复、细二值检测、带边缘检测和聚类四步组成的宽带频谱感知过程。仿真结果表明,在低于奈奎斯特采样率的情况下,所提出的频谱感知方法能够正确定位频谱空穴。

Wideband spectrum sensing in modulated wideband converter based cognitive radio system
Wideband spectrum sensing is a fundamental problem in cognitive radio networks. In this paper, a wideband spectrum sensing procedure which consists of four steps, i.e., coarse support recovery, fine binary detection, band edges detection and clustering, for modulated wideband converter (MWC) based cognitive radio system at sub-Nyquist rate is proposed. Simulations show that with a sub-Nyquist sampling rate, the proposed spectrum sensing procedure can locate spectrum holes correctly.
