Stochastic Resonance Effects for Aperiodic Pulse Signal

为了有效地实现随机共振效应在非周期冲击信号检测中的应用,论文研究了数值计算初值以及双稳态系统结构参数对随机共振效应的影响,对比了非周期冲击信号随机共振检测系统的阱内与阱间效应.通过仿真,应用随机共振阱内效应对被噪声干扰的钻杆声波通讯信号进行检测,验证了随机共振效应检测非周期冲击信号的实用性.

In order to achieve the stochastic resonance effect can be used for the aperiodic pulse signal detection effectively,The paper,which studied the impact of the bistable system structure parameters and the numerical initial value on the stochastic resonance effect in this paper and compared the aperiodic pulse signal detection method of stochastic resonance between the trap and the well effect.The acoustic communication signal submerged in noises based on stochastic resonance trap effect through the simulation,and the result shows that the stochastic resonance effect is useful to detect the aperiodic pulse signals.
