47066 最后,接收端根据收到的有损数据利用压缩感知的方法重构原始信号。 Now, the raw signal could be recovered from the lossy data at the receiver node using CS reconstruction algorithms.
47067 进一步根据压缩感知重构和无线通信的相关原理,推导出允许使用的发送端最小压缩率和最大分组长度。 Furtherly, according to the theory of CS reconstruction and the formula of packet reception rate in wireless communica-tion, the minimum compression ratio and the maximum packet length allowed were obtained.

47069 在车联网中,同时使用多个虚假身份的 Sybil 攻击,在网络中散布虚假消息,都易造成资源的不公平使用和网络混乱。 In VANET, the Sybil attack simultaneously using multiple forged identities can easily cause the injustice ofresource usage and make networks in a mess by distributing false messages.
47070 针对这一问题,提出快速识别车辆虚假位置的事件驱动型轻量级算法, To solve this problem, an event-drivenlightweight algorithm was proposed, which could identify vehicles false position quickly.
47071 当车辆出现在另一车辆的安全区域内,启动快速识别两车辆是否重叠的几何交叉模型(GCR, geometrical cross-recognition)算法,检测声称虚假位置的错误行为; When one vehicle appeared in-side another’s safety zone, a geometrical cross-recognition algorithm to calculate the overlap between vehicles to detectfalse position claiming was presented.
47072 同时,根据证实车辆收集的邻居范围内的局部车辆,建立位置偏差矩阵(PDM, positiondeviation matrix),进一步识别交叉车辆中的 Sybil 节点。 At the same time, according to the neighbors within the confirming vehicle’s radiorange, position deviation matrix was established further to identify the Sybil node of two overlap vehicles.
47073 性能分析和仿真实验表明,安全区域驱动下的轻量级算法识别速度快,检测率高,在车辆定位误差较低时性能更好; The perfor-mance analysis and simulation results show that the lightweight algorithm driven by safety zone demonstrates fast identi-fication and high detection rate, especially when GPS error is very low.
47074 安全区域的引入也均衡了车辆密度过大时造成的通信负载影响, The imported safety zone can also balance thecommunication load impacting by heavy vehicular density.
