We give out the coordinative estimations of signal & noise . this method is applicable for all additive white noises . and it can be used to identify signal simultaneously 給出了信號(hào)與噪聲的聯(lián)合估計(jì),該方法適用任意加性白噪聲,且可同時(shí)對(duì)信號(hào)進(jìn)行識(shí)別,有一定的普遍意義。
The phenomenon of noise - induced transport of brownian particles in periodic and quasi - periodic systems with coupling between multiplicative colored noise and additive white noises is investigated 在含有耦合的乘性色噪聲和加性白噪聲的周期性和準(zhǔn)周期性系統(tǒng)中,我們分析了噪聲誘導(dǎo)的布朗粒子的輸運(yùn)現(xiàn)象。
Secondly , combining the unified colored noise approximation and the functional analysis , the steady state distribution function is derived when both multiplicative colored noise and additive white noise are included in a bistable system with colored coupling between two kinds of noise . through the two - state theory , the expression of signal - to - noise ratio ( snr ) is obtained . the phenomenon of stochastic resonance is investigated 其次,我們綜合運(yùn)用統(tǒng)一色噪聲近似和泛函近似的方法,推導(dǎo)了含有乘性色噪聲和加性白噪聲,并且兩種噪聲之間的耦合為色噪聲的雙穩(wěn)非線(xiàn)性系統(tǒng)的定態(tài)分布摘要不同類(lèi)型的色噪聲對(duì)非線(xiàn)性光學(xué)系統(tǒng)的影響函數(shù),然后通過(guò)雙態(tài)理論求出系統(tǒng)信噪比的解析表達(dá)式,對(duì)系統(tǒng)的隨機(jī)共振現(xiàn)象進(jìn)行分析。
