Design of a Tunable Integrated Roofing Filter for LTE Bands
Roofing Filter Tunable LTE Varactors Passive Filter
2014/12/8
The advent of new standards in wireless communication like the Long Term Evolution (LTE) has resulted in a need for newer and better design of receivers for wireless communication systems, the first s...
针对骨干网上异常检测的特殊要求，提出了一种基于Filter-ary-Sketch数据结构的异常检测方法。该方法通过Filter-ary-Sketch实时记录网络流量信息，然后每隔一定周期进行基于多维熵值的异常检测。如果出现异常则根据Filter-ary-Sketch记录的流量信息进行异常点定位，最后利用Bloom Filter中记录的源IP信息进行恶意流量阻断。该方法能够检测多种类型的网络攻击，且...
基于Kalman滤波农用车辆导航定位方法（Positions Research of Vehicle Navigation System Based on Kalman Filter）
车辆导航 定位 Kalman滤波
2009/11/3
因RTD-GPS定位精度不能满足农田导航作业的需要，研究了一种提高农用车辆自动导航定位精度的方法。建立天线补偿模型，对GPS天线晃动引起的误差进行了补偿；建立基于Kalman滤波模型，融合多传感器信息；使用自主开发的基于VRS的GPS接收机，作为RTD-GPS。将RTD-GPS、电子罗盘以及速度传感器获得信息进行Kalman滤波，其结果和高精度GPS数据进行了比较。实验证明，直线跟踪中，平均偏差由...
Wiener's Loop Filter for PLL-Based Carrier Recovery of OQPSK and MSK-Type Modulations
Wiener's Loop Filter PLL-Based Carrier Recovery OQPSK MSK-Type Modulations
2009/9/4
This letter considers carrier recovery for offset quadrature phase shift keying (OQPSK) and minimum shift keying-type (MSK-type) modulations based on phase-lock loop (PLL). The concern of the letter i...
