摘要
在对双稳随机共振系统及其数学模型进行简单的介绍后,给出了将该系统应用于实际的基带信号检测应用模型和仿真结果。对将该模型应用于基带信号检测的随机共振物理机制进行了深入的分析,结果表明,在上述基带信号检查中,随机共振是信号,噪声和双稳系统共同作用的结果,三者缺一不可。
The bi-stable stochastic resonance ( SR) system as well as the mathematical model of the system is introduced briefly. The model applying the SR system to practical base-band signal detection is proposed and the simulation result is presented. The physical mechanism of the model is analyzed in detail and the results show that the signal, the noise and the bi-stable system cooperate with each other when the SR phenomenon happens.
