| 摘 要： | 为了能对提高高斯色噪声中正弦信号的检测能力,提出了二阶自相关和四阶累积量预处理的信号相位匹配检测法.仿真结果表明,高斯色噪声中四阶累积量预处理的信号相位匹配检测法的检测性能接近于高斯白噪声下匹配滤波器,优于二阶自相关的信号相位匹配检测法的检测性能,更优于的信号相位匹配的最小二乘检测器.

| Abstract: | Use Reassign-Smooth-Pseudo-Wigner-Ville Distribution(RSPWVD) as time-frequency analysis tool disposal multi-component signal with arbitrary form frequency modulation law.Smooth can retrain cross-term of signals,but the signal-terms be smoothed at the same time.Reassign can time-frequency concentration.Use the algorithm presented in this paper analysis image of RSPWVD.Simulation experiments indicate that the algorithm can separate the instantaneous frequency of each signal component on the condition that abs... |
