摘要
随着时代的进步和科技的发展,人们对于现有的频谱资源的需求量正在逐渐增大。为了能够尽可能的提高现有频谱的利用率,认知无线电技术由此产生,认知无线电通信的重要技术之一是频谱感知技术。常规的频谱感知技术往往有诸多局限性,引入拟合优度的概念,研究基于拟合优度的频谱感知技术的性能,分析各种变量对检测结果的影响。
With the progress of the times and the development of technology, the demand for the existing spectrum resources is gradually increasing.In order to improve the utilization of the existing spectrum as far as possible, the concept of cognitive radio is put forward, and one of the important technologies of cognitive radio communication is the spectrum sensing technol- ogy.Conventional spectrum sensing technology often has many limitations.In this paper, the concept of goodness of fit is in- troduced, the performance of spectrum sensing technology based on the goodness of fit is studied, and the influence of vari- ous variables on the detection results is analyzed.
