Many man - made signals in communications , radar , sonar and other fields " exhibit cyclostationarity 在通信、雷达、声纳等领域中，许多人工信号都具有循环平稳性。
The main purpose is to discuss the stationarity of two classes of nonstationary processes after wavelet transformations 摘要主要讨论了两类非平稳过程小波?换后的平稳性。
Based on the cyclostationary characteristic , a novel time delay estimation method has been proposed in this thesis 基于这样的特点本文给出了基于循环平稳性的时延估计方法。
( 4 ) the effect of track elasticity on ride comfort of vehicle and train are systematically studied in the thesis （ 4 ）系统地研究了轨道弹性对车辆和列车运行平稳性的影响。
They can be well used to investigate the stability , dynamic curving behavior and ride comfort of the train system 模型e和模型f可用于研究列车系统的运动稳定性、运行平稳性及动态曲线通过性能。
Unstable random process was passed test to time list error . aiming error was confirmed on unstable random process 对方位测量在试验时间段内，进行了非平稳性检验，证实了瞄准误差属于非平稳性的。
Speech signal , carrying a large amount of information , is so complex with the character of non - stationary and time - varying 携带着大量信息的语音信号本身是非常复杂的,并且具有非平稳性、时变性等特征。
In order to meet the requirement of high - precision orientation and moving smoothness , subdivision driving of stepper motor is adopted 为了适应一些领域中高精度定位和运行平稳性的要求，出现了步进电机细分驱动技术。
In order to guarantee the stationarity and safety of trains running in high - speed railway , strict limitation on long - term camber of bridges is needed 为保证列车行驶的平稳性和安全性，高速铁路桥梁的徐变上拱度有十分严格的限值。
On the other hand , the safety and stability of moving vehicles on bridge is the important factors to evaluate the parameters of dynamic design 另一方面，桥梁上运行车辆的平稳性和安全性又是评价结构动力设计参数合理与否的重要考虑因素。
