认知无线电中基于谱熵的频谱感知方法
Spectral-Entropy based Spectrum Sensing in Cognitive Radio
频谱感知技术是认知无线电技术中的一项重要的技术，本文中，我们提出了一种基于谱熵的检测主用户信号的方法，此方法不需要主用户信号的先验知识，能更好的应用在实际系统中。通过仿真，即使接收主用户信号的信噪比较小时，我们提出的方法也能很好的检测到主用户的信号
Spectrum detection is the key technology of cognitive radio. In this paper, we present a simple technique for detection of primary users in cognitive radio networks with unknown the prior knowledge of primary users. It Can be better used in the actual system. Through the simulation, even though the SNR(Signal-to-Noise) of the received signal is low, the detector based spectral-entropy also has the ability to distinguish the signal from noise.
