摘要
针对强噪声背景中的弱信号检测问题,在经典随机共振处理方法的基础上,利用小波良好的去噪特点,提出了小波去噪加随机共振检测弱信号的方法.理论分析和仿真结果表明,该方法优于传统的随机共振处理方法,可获得更大的输出信噪增益.
In order to resolve weak signal detection in stronger noise background, on the basis of stochastic resonance processing and wavelet analysis, this paper proposes a modified stochastic resonance processing method. Both its theoretic analysis and simulations are done, and the results show that the performance of the modified method outperforms that of the classical stochastic resonance method.
