50637 实验结果表明，与现有方法相比，对于全仿射形变条件下的SAR图像配准，本文所述算法可以提取到更多的匹配特征点，因而具有更好的配准性能。 The experimental results show that, compared with existing methods, for the whole affine deformation under the condition of SAR image registration, this article described algorithm can extract more matching feature points, thus has better matching performance.
50638 基于预留机制的服务器动态开启/关闭(dynamic powering on/off servers，DPS)策略采用静态设置的任务请求数阈值，可能造成服务器状态频繁切换从而导致性能下降、能耗上升。 Reserve based on the mechanism of dynamic server open/close (dynamic powering on/off the servers, the DPS) strategy to adopt static task requests threshold, the switch may cause server status frequently resulting in performance degradation, increase energy consumption.
50639 对此，提出一种基于动态阈值的服务器唤醒策略。 In this paper, a kind of server wake-up strategy based on dynamic threshold.
50640 首先，用具有不耐烦任务的排队模型对云计算系统的任务调度进行建模，分析系统中的平均任务背叛数和能耗成本，提出任务请求数阈值动态调整策略; First of all, with impatient task queue model of task scheduling in cloud computing system with modeling and analysis system of the average number of task betrayal and energy costs, and put forward the task requests threshold dynamic adjustment strategy;
50641 然后，根据服务器所在冷点区域和当前关闭时长选择服务器进行唤醒。 Then, based on the server where the cold spot area and the current closing time select server to awaken.
50642 仿真结果表明，与基于静态阈值的服务器唤醒策略相比，本文策略能够保证任务的平均响应时间，并有效降低云计算系统的能耗开销。 Simulation results show that compared with the server wake-up strategy based on static threshold, this strategy can guarantee the average response time of tasks, and effectively reduce the energy consumption of cloud computing system overhead.
50643 在高速移动环境下，宽带正交频分复用(orthogonal frequency division multiplexing，OFDM)系统在传输过程中因频率偏差都会导致严重的子载波间干扰(inter-carrier interference，ICI)。 In high-speed mobile environment, broadband orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) systems in transit due to frequency offset will lead to serious interference between subcarrier (Intel - carrier interference, ICI).
50644 本文在分析频偏导致ICI成因基础上，结合共轭消除方案和编码权值优化方案，提出一种有效的ICI自消除新方案。 In this paper, based on the analysis on causes deviation cause ICI, combined with the conjugate eliminate scheme and encoding a weight optimization scheme, proposed an effective ICI from eliminating the new scheme.
50645 仿真结果表明，所提出的方案在较大频偏范围内具有较高的载干比(carrier-to-interference ratio，CIR)和较低的误比特率(bit error rate，BER)， The simulation results show that the proposed scheme in larger frequency range with high load dry than (carrier - to - interference thewire, CIR) and lower bit error rate (bit error rate and BER),
50646 且能有效消除传统自消除编码性能的"平层效应"，进而获得了系统性能的改善。 and can effectively eliminate the traditional eliminate coding performance "flat layer effect", then to improve the performance of the system is obtained.
