摘要

文章提出一种更精炼的能量检测算法(Improve Energy Detection,IED),该算法能避免瞬时信号能量下降造成的错误检测。实验结果表明,它能够在保持类似复杂度和计算成本水平的同时优于传统能量检测算法,精确判别信道中是否只存在噪声,有效地降低了能量检测的复杂度,提高了检测的可靠性。
        In this paper, a more Improved Energy Detection(IED)is proposed, which can avoid the false detection caused by the decrease of instantaneous signal energy. The experimental results show that the proposed algorithm is superior to the traditional energy detection algorithm while maintaining the similar complexity and computational cost. It can accurately determine whether there is only noise in the channel and effectively reduce the complexity of energy detection, thus the reliability of detection is improved.
