The motion of plunger of oleo damper excited by colored gaussian noise with exponential correlation time is governed by first order nonlinear differential equation 摘要油液阻尼器受指数型高斯色噪声外激励时,活塞在油腔内的运动可用一阶非线性动力学方程描述。
The stochastic resonance appears as the value of the coupling coefficient between two noise terms is increased . when the noise correlation time t is increased , the snr is changed f 信噪比在单峰和双峰之间的跃迁对乘性噪声关联时间: 、和噪声之间的祸合系数兄的依赖程度更强于对祸合噪声关联时间几的依赖。
It is found that the signal - to - noise ratio ( snr ) of the system is affected not only by the coupling coefficient between two noise terms , but also by the noise correlation time t 研究结果表明,系统的信噪比不仅受到两种噪声之间的祸合系数兄的影响,而且受到噪声相关时间公的影响,即噪声有色性的影响。
We proposed a new time acquisition method , called adaptive subsection correlation time acquisition method of mc - cdma system , the subsection correlation length is adapted according to the probable frequency offset 提出了用于mc - cdma系统的新型时间同步法一自适应分段相关时间同步法。它根据估计频率偏移自适应调整分段相关长度。
The expressions for correlation functions , power spectrum and correlation time of the intensity of a single - mode laser driven by two white noises with a exponential function correlation form were calculated by linear approximation method 应用线性近似方法,计算了具有指数形式关联的两白噪声驱动下单模激光光强的关联函数、功率谱及关联时间。
