一种适用于超宽带脉冲信号检测的改进CUSUM算法
An Improved CUSUM Algorithm for UWB Pulse Signal Detection
摘要
Abstract
Quickest detection technology or exactly the improved Cumulative Sum(CUSUM)is applied to ultra-wide band(UWB)signal detection . First,the UWB pulse signal distribution after multi-path fading channel is analyzed . Then an improved CUSUM algorithm adaptive to UWB pulse signal detection is proposed . Both theo-retical analysis and simulations prove that the improved algorithm conquers the SNR wall phenomenon,with small detection delay and low realization complexity . Under the same false alarm constraint,the detection per-formance of proposed algorithm is much better than that of energy detection .关键词
