The invention discloses a data transmitting method, a device and a system in a time division duplex system, which is used to solve the problem in the prior art that downlink data among adjacent cells interfere to uplink data; the method comprises that: a blanket channel of a whole cell or a high-power transmit channel is mapped to OFDM symbols of a downlink time slot in a transmit frame, a guard interval in the transmit frame and the OFDM symbol on a time domain space OFDM symbols which are not mapped to any of the blank channel of the whole cell and the high-power transmit channel; an uplink control channel is mapped to OFDM symbols of an uplink time slot in the transmit frame, the guard interval and the OFDM symbols for mapping the uplink control channel on the time domain space OFDM symbols which are not mapped to uplink control channel; the OFDM symbols of the transmit frame are transmitted; the invention is adopted to avoid the interference between the downlink data and the uplink data among the adjacent cells.

Meanwhile, it could be seen that there does not exist a confidence interval with width less than 0.5 because of the property of Poisson distribution. Based on these conditions, the author mainly carried out research into two aspects of this problem as follows. Firstly, by numerical and theoretical analysis, the author compares some existent confidence intervals, for example,"exact" confidence interval, Wald confidence interval and Bayesian confidence interval, and finds some deficiencies points of the confidence intervals, whose modification version has been proposed .Also, several better confidence intervals such asare also presented .Secondly, for given confidence coefficient and interval width, the author constructs a class of asymptotical two-stage interval estimate procedures. At the same time, under varies restriction of confidence coefflcientent interval width, the optional sample size of the first stage has been computed by numerical computation. The numerical computation shows that the method considered in this dissertation have good properties and applied value.
同时,由于Poisson分布的特性,我们知道不存在其参数区间长度小于0.5的置信区间,基于这些情况,我们主要展开了以下两个方面的研究:一是利用数值计算分析与理论分析的方法对现有的若干置信区间如"精确"置信区间,Wald置信区间,Bayes置信区间等进行分析比较,发现了一些缺陷,针对这些缺陷,我们进行适当的修正,并得到几种性质较好的置信区间如:修正大样本区间Jeffreys原则下置信区间二是针对已给定的置信系数与区间长度,我们提出了一种渐近的两阶段区间估计程序,并利用数值计算的方法,在各种置信系数与区间长度限定下,算出了最优的第一阶段观测次数,大量数据表明,本文考虑的方法性态良好,具有应用价值。

It allows each edge of a graph data set to be with different interval-gap value. For example, given a graph with n edges, the interval-gap concept provides n interval-gap values, Min_Gap and Max_gap, for these edges correspondingly. By incorporating this concept into the graph mining, discovering frequent sub-graph with time constraints can be more effective.
在本论文中提出了区间间隙的概念,主要即是由固定的Min_Gap、Max_gap将之修改调整为弹性的Min_Gap与Max_gap,此区间间隙弹性的地方即在於图形资料集里的任两个节点所串连的边皆会有不同的区间间隙,也就是一个具有n个边的图形里,将会有n个不同的区间间隙值,也就是Min_Gap与Max_gap,这样的作法对於具有时戳性质的图形探勘将更有效益

Firstly, This paper processes geometry filtration based on character of orbit's apogee and perigee after orbit model is analyzed and based. Secondly Space Debris is separated into two kinds, coplanar and not coplanar according as location interrelation of target and debris. In Dynamic filtration's processing, considering prediction time limit and orbit perturbation, secular effects which have increaser effect is considered so that some need catching danger time point is appeased, some law about time when target and debris pass intersectant line each other is inferred, when debris and object are in different plane and some similar law also is inferred otherwise. The time list is arithmetical progression. These laws can improve calculation efficiency remarkably; Lastly orbit predict is a course approaching least distance. Danger time point in the last step become beginning time point from which debris and object's position and velocity are calculated by SXP4 Model which is an analytic model.By result, determine that relative movement trend is closer or apart, farther calculate the interval apart from time when predictive least relative distance occurs. Least relative distance and time when least distance occurs is calculated finally. It is a fast approach course adopting varied interval.

This thesis proposes a novel method of retiming E1 signal of the SDH output and using it as a reference synchronization signal for Trunking Gateway. The proposed retiming method can generate the E1 signal of TG input in comply with the maximum relative time interval error requirement of 52.5ns specified in the PRC-Generation standard. The method successfully reduces the E1 signal error level to a smaller margin of 300ns than that of the PRC-output standard.
