说明:  基于能量检测的频谱感知.由于实际信道中的多径和阴影效应,单个认知用户频谱感知的性能受到影响,因此需要靠不同用户间的协同频谱感知来对抗多径和阴影效应。本设计要求在文中采用一种协作机制,即两用户进行协作频谱感知,提高主用户的检测率,减少检测时间,并且得到捷变增益。要求给出仿真结果。
(spectrum sensing in cognitive radio based on energy detection.As the channels in diameter and shadow, not a single user spectrum of capabilities and therefore need different between a user to the spectrum is perceived as more and the effect. this design for the use of a coordination mechanism, the two users collaborate spectrum, the detection rate of increase and decrease the test of time and get a change requires immediate gain. some emulation. )
