This paper focus on the variable rate qam for mobile radio 本文针对移动通信中的变速率qam调制进行了较为深入的研究。
Variable rate code vrcblp 变速率码
Creep rate unit 蠕变速率单位
Rate of creep 潜变速率
For the later , in this paper we study in the services of fixed rated and variable rated 对于后者,本文从固定速率业务和变速率业务两方面进行研究。
Since a phased array radar can direct the radar beam in any direction without inertia , it can perform adaptive sampling of target trajectories 相控阵雷达可以在任何方向无惯性改变雷达照射方向,这使得它能进行变速率的采样。
With the booming of the third generation mobile telecommunication , the variable rate speech coding technology , which is the core of it , has been widely studied during recent years 随着第三代移动通信系统的迅猛发展,作为其话音业务的核心技术,变速率语音编码技术在近年来得到了广泛的研究。
Homogenization techniques in multi - scale analysis , the description of domain switching and the effect that the rate of domain switching has on the macroscopic behavior of ferroelectrics are the main subjects discussed in this paper 跨尺度分析中多相材料的均匀化理论、铁电体畴变描写和畴变速率对铁电体宏观行为的影响是本文主要讨论的问题。
It is the first time to use the conventional espi system ( neither phase shifting nor carrier is used ) to continuously analyze the super low frequency vibration with high quantitative in the world 在火箭固体燃料动态力学特性研究中,时间序列法成功的给出了固体燃料的蠕变曲线和蠕变速率曲线,并且给出了其热变形和蠕变不同时刻的全场位移分布。
It has been discovered that the deformation in the primary creep regime can well described by eqution : - 0 = atm , moreover , the eqution : = a n exp ( - q / rt ) can be used to interpret phenomenally the relationship between the steady - state creep rate and stress , temperature 蠕变的第一阶段也就是减速蠕变阶段的蠕变变形可用? _ 0 = at ~ m来描述。可以唯象地解释稳态蠕变速率和蠕变应力和温度之间的关系。
