摘要

重点分析了主用户(PU)信号到达感知区间对局部频谱感知性能的影响。信号在传感时间内到达采样点的概率是均匀分布的。在这种情况下，分析了传统能量检测方法的性能退化问题。此外，为了提高性能，提出了一种与复合能量检测相配合的信号到达时间估计方法。利用数学分析和数值模拟对所得到的频谱感知性能进行了研究和验证。

A method to enhance the reliability of the local spectrum sensing

This paper is focused on analyzing the effects of primary user (PU) signal arrival in the sensing interval on the local spectrum sensing performance. The probability for signal arrival at a sample in the sensing time is uniformly distributed. In this case, the performance degradation of the conventional energy detection (CED) method is analyzed. Furthermore, in order to enhance performance, an approach of estimating the signal arrival time is proposed to cooperate with the composite energy detection. The mathematical analysis and numerical simulation are employed to investigate and show the resulted spectrum sensing performance.
