| 摘 要： | 讨论高斯白噪声背景下基于周期图法的残留载波BPSK(RC-BPSK)信号的检测问题。标准周期图法在正弦信号检测中的性能最优,但是在RC-BPSK信号检测中的性能却不佳;能量检测法只在信噪比很低的情况下性能较好;在信噪比较高时,虽然Bartlett法有较好的性能,但需要分段多次计算周期图,不利于与其他检测方法配合使用。文中在频谱匹配法的基础上发展了一种频谱相关检测方法,仿真结果表明该方法可以获得和Bartlett法相似的性能,同时只需要计算一次周期图。

| Abstract: | Detection of Residual Carrier BPSK(RC-BPSK) signal in white Gaussian noise based on periedogram is dis- cussed.Standard periodogram has poor performance in the RC-BPSK detection though it is optimum in the tone detection.Energy detector has good performance only at very low SNR.Although Bartlett method gives better resnlts at higher SNR,it is not conven- ient to be used together with standard periodogram.Based on the spectrum matching method,a spectral correlation detector is devel- oped in this paper.Simul... |
