认知无线电中基于波型与能量的联合检测方法
Combined Detection Method Based on Waveform and Energy in Cognitive Radio
摘要
Abstract
To solve the deficiency in efficiency, complication and utility of the existing main sensing algorithms, this paper analyzes a way of spectrum sensing derived on waveform, based on which it puts forward a combined detection method associated with energy sensing.According to the numerical analysis and simulation results, it concludes that the combined sensing can effectively detect the spectrum hole and meanwhile,overcome the problem of poor detection effect under low signal to noise ratio, which makes it better than waveform detection and energy detection in detection efficiency, reliability, stability and other performance.关键词
