摘要: In this paper, the conventional primary user signal detection algorithms’ common weakness and advantages of scheme based on CUSUM algorithm are analyzed. To avoid statistic’s dithering which increases delay, an improved with a slipped pretreatment window is proposed. Simulation shows that delay decreased obviously.
