47286 尽力而为的 IP 网络难以满足日益提高的服务质量需求，亟需研发一种兼容现有 IP 软硬件资源的 QoS 控制机制。 It was difficult to meet the increasing demand of quality of service (QoS) for the best-effort IP network, so itwas urgent to develop a kind of QoS control mechanism that was compatible with the existing IP software and hardwareresources.
47287 为此，提出了一种基于软件定义网络的区分服务优先权的流控机制 PriQoS。 Therefore, a priority-differentiated control mechanism based on the software defined networking called PriQoSwas proposed.
47288 当网络资源紧缺时，使用基于业务流综合优先权的多队列带宽分配算法来满足高优先权流的带宽需求； When the network resource was scarce, a multi-queue bandwidth allocation algorithm based on theintegrated priority of service flow was used to meet the bandwidth requirement with high priority flows.
47289 PriQoS 部署在网络边缘，无需修改端系统应用程序和核心网路由器， PriQoS wasdeployed on the network edge, which was no need to modify applications in the end systems and routers in the corenetwork.
47290 具有易于部署、与 IP 应用和设备兼容的优点。 The mechanism has advantages such as easy to deploy and being compatible with the IP applications anddevices.
47291 实验结果表明 PriQoS 机制能够优先保证高优先权业务的服务质量。 Experimental results show that the PriQoS mechanism can guarantee the QoS of higher priority services.
47292 针对压缩感知中噪声折叠现象严重影响稀疏信号重构性能的问题，提出一种基于选择性测量的压缩感知去噪重构算法。 In order to reduce the effect of noise folding (NF) phenomenon on the performance of sparse signalreconstruction, a new denoising recovery algorithm based on selective measure was proposed.
47293 首先从理论上解释了压缩感知中噪声折叠现象； Firstly, the NFphenomenon in compressive sensing (CS) was explained in theory.
47294 然后提出一种基于测量数据的特征统计量，推导分析其概率密度函数， Secondly, a new statistic based on compressivemeasurement data was proposed, and its probability density function (PDF) was deduced and analyzed.
47295 并基于此构造一种噪声滤波矩阵，用于优化测量矩阵， Then a noisefilter matrix was constructed based on the PDF to guide the optimization of measurement matrix.
