：该文首先研究了单认知用户能量检测算法的检测性能和检测灵敏度与检测时长和噪声短时间内平均功率波
动性之间的关系，得出检测性能和检测灵敏度随噪声短时间内平均功率波动性的增大而急剧下降的结论，在低信噪
比时尤为明显；针对检测性能和检测灵敏度随噪声短时间内平均功率波动性的增大而急剧下降，提出了基于多用户

These
cooperations are facilitated by dynamically and opportunistically assigning one of the secondary users as a relay to assist the other
one, which results in more efficient spectrum hole detection. Also, we investigate the impact of erroneous
