一种基于子时隙的联合频谱检测算法

A Mini-Slot Based Coordinated Spectrum Sensing Algorithm

频谱检测算法的性能是认知无线网络的关键指标。在传统频谱检测算法中,单一检测时隙仅被用于检测一个信道。文章提出将检测时隙划分为多个子时隙,且每个子时隙独立检测一个信道,通过理论与仿真证明子时隙联合频谱检测算法优于传统频谱检测算法。

The performance of spectrum sensing algorithm is the key to cognitive radio network. In traditional spectrum sensing, a whole sensing duration would only be used to sense one channel. In this paper, the sensing duration is proposed to be divided into many mini-slots, and each mini-slot can be used to sense one channel has a better performance than the traditional method.
