| 摘 要： | 频谱感知是认知无线电的关键技术之一。讨论了一种利用信息熵的频谱感知方法,并以IEEE 802.22的一种主用户信号对算法性能进行了仿真分析。仿真结果表明这种方法能够克服噪声功率不确定性的影响,而且对信息熵估计时的参数选择不敏感,在低信噪比下能够获得较好的检测性能。

| Abstract: | Spectrum sensing is one of the key technologies for cognitive radio.A spectrum sensing method exploiting information entropy is introduced and one of the primary signals in IEEE 802.22 is used for performance analysis.Simulations show that this method can overcome the problem of noise power uncertainty,Which is insensitive to the parameter choice in entropy estimation,and can obtain good detection performance in low signal-to-noise ratio scenarios. |
