| 摘 要： | 设计了一种新的频谱空洞的检测方法,基于谱相关分析的理论,在循环相关匹配滤波器的基础上,采用单通道信号的检测统计量作为统计判据,用Bartlett(巴特利特)窗周期图法进行功率谱估计,并进行了蒙特卡罗仿真.仿真结果表明,在低信噪比的情况下,该检测方案具有良好的检测性能.

| Abstract: | This article introduces one new spectrum hole sensing method based on the circular correlation matched filter's foundation,taking the single channel signal decision statistics as statistical criterion,uses(Bartlett) the window periodogram law carries on the power spectrum with Bartlett to estimate,and uses the Monte Carlo simulation.The simulation result indicated that in the low SNR situation,this detection plan has the good detection performance. |
