摘要 临界混沌状态的周期振子对噪声具有免疫力,而对微弱的正弦信号或相位编码信号比较敏感。根据这种特 性,可以检测出淹没在强噪声背景下的微弱正弦信号或相位编码信号并估计其频率。 The periodic oscillators at critical state are immune to noise and have sensitive dependence on weak sine signals or phase-coded signals at the same time. According to the characteristic, we can detect weak signals buried in the noise environment and estimate their frequency.
