The characteristics of Lorentzian distribution in the power spectrum of a stochastic resonance ( SR) from a bistable system have been investigated, and then the viewpoint of producing an identifiable SR peak only at the lower frequency area where the power energy being concentrated has been proposed.
研究了双稳系统随机共振频谱的洛伦兹分布特征,得出在谱分布能量较集中的低频区才能产生可辨识的随机共振谱峰。
To improve beamforming under low signal-to-noise ratio, a method based on stochastic resonance ( SR) in a bistable model is investigated by using a frequency scale transformation method.
为了改善低信噪比下波束形成的性能,从双稳态随机共振模型出发,提出了利用频率尺度变换,将随机共振和波束形成结合起来的算法。
