24135 分布式压缩感知(Distributed Compressed Sensing, DCS)是在无线传感器网络(Wireless Sensor Network, WSN)中减少数据传输量、降低能量消耗的有效手段。 Distributed Compressed Sensing (DCS) is an effective means to reduce the amount of data transmission and energy consumption in Wireless Sensor Network (WSN).
24136 该文面向分簇 WSN,提出层次化分布式压缩感知(Hierarchical Distributed Compressed Sensing, HDCS)。 Hierarchical Distributed Compressed Sensing (HDCS) is proposed for clustering WSN.
24137 在利用簇内 DCS 消除簇内时间、空间冗余的基础上,利用簇间 DCS消除簇间空间冗余,减少簇头的数据发送量。 It eliminates the temporal-spatial redundancies among data collected by the cluster members with the intra-cluster DCS, and eliminates the spatial redundancies among clusters with the inter-cluster DCS.
24138 针对分簇 WSN 采集信号的结构化稀疏特性,建立块稀疏簇内联合稀疏模型与块稀疏簇间联合稀疏模型,提出 HDCS 观测方案与层次化联合重构算法。 According to the signal's structured sparsity, a block-sparse intra-cluster joint sparsity model and a block-sparse inter-cluster joint sparsity model are constructed. Then, a hierarchical measurement scheme and a hierarchical joint reconstruction scheme are proposed for HDCS.
24139 仿真结果表明,与普通 DCS 相比,HDCS 在保证重建信号质量的同时,能够有效减轻簇头的通信负担,并显著降低 Sink 上的信号重构时间。 Experimental results show that compared to general DCS, HDCS can relieve the transmission burden in the network effectively, without lowering the quality of the reconstructed signal. Moreover, it can reduce the signal reconstruction time at the Sink observably.
24140 该文提出一种新型的具有多谐振结构的单层微带反射阵单元,是由 6 个振子以一定的间隔平行放置组合而成,该单元具有良好的线极化特性。 A novel single layer microstrip reflectarray element with multi-resonance structure is presented. The element is composed of six dipoles which are placed in parallel at a certain distance.
24141 采用高频电磁仿真软件 HFSS 对单元的各个参数进行优化分析,使得单元的反射相位曲线在两个频段内均具有良好的线性度。 The element has good linear polarization properties. Ansoft HFSS is used to optimize the parameters and linear reflection phase curves in two bands are achieved.
24142 根据此单元设计了一个工作在 X/Ku 波段的偏馈双频双极化微带反射阵天线,在两个频段内采用同一个角锥喇叭天线作为其馈源。 A dual-band dual-polarization reflectarray composed of the elements is designed, fabricated and measured. The reflectarray is offset fed by only one horn antenna for both bands in two orthogonal polarizations.
24143 将此反射阵天线进行加工并测试,测试结果表明,在 X 波段中心频率 10 GHz Ku 波段中心频率 13.58 GHz 处,天线均具有良好的辐射性能。 The proposed reflectarray operates in two frequency bands within X band centered at 10 GHz and Ku band centered at 13.58 GHz. Measured results show good radiation performance in both bands.
24144 实测和仿真结果吻合较好,证明了该反射阵天线具有良好的双频辐射性能。 A well coincide is obtained between the simulated and measured results, which demonstrate the desirable dual-band dual-polarization radiation performance of the reflectarray.
