NETGEAR Brings Wireless Internet Connectivity Home: Kalman's company is currently housed in offices on a single floor. Although he does not need a NETGEAR Wireless Range Extender at work, he has already replaced eZCom's previous Wireless Router with a NETGEAR 108 Mbps Wireless Router. The company also uses a number of other NETGEAR products to power...; Tags: Internet, Wireless Internet, NetGear, Wireless, Kalman, Home Networking, Networking, Personal Technology; Case studies

A Nonlinear Look at Trend MFP Growth and the Business Cycle: Results From a Hybrid Kalman/Markov Switching Model: This paper uses a nonlinear hybrid Kalman/Markov model to estimate trend MFP growth and compares the results from this model with the standard linear Kalman filter approach used elsewhere in the literature. The estimated parameters of the hybrid model suggest strongly that the business cycle is nonlinear, with four out...; Tags: Federal Reserve Board, Business; White papers 2005-02-22
Blind Detection of CDMA Signals Based on Kalman Filter: This paper studies detection of CDMA signals based on Kalman filter. In the absence of both training symbols and the knowledge about multipath channel parameters, the system can be exactly fit into the Kalman model. By defining combination of channel and transmitted signals as state variables, the state transition matrix...; Tags: Matrix, CDMA, Signal, University Of California, Workforce Management, Cellular Phones, Human Resources, Consumer Electronics, Personal Technology; White papers
Phase Noise Suppression in OFDM Using a Kalman Filter: The performance of an OFDM system can be strongly degraded by the presence of random phase noise especially if a system design targets high data rates at high carrier frequencies. Phase noise causes constellation rotation, the so called Common Phase Error CPE, and InterCarrier Interference ICI. This paper introduces an...; Tags: OFDM, Wireless; White papers
Joint Time-Domain Tracking of Channel and Frequency Offset for OFDM Systems: This paper addresses the problem of joint channel and frequency offset estimation and tracking for OFDM systems. The proposed method is based on Extended Kalman filtering. The channel taps and the frequency offset are estimated in time-domain while equalization is performed in frequency domain. Simulation results demonstrate accurate tracking capability...; Tags: Frequency, Channel, Method, OFDM, Wireless; White papers 2006-03-21

3D Model Acquisition by Tracking 2D Wireframes: This paper presents a semi-automatic wireframe acquisition system. The system uses real-time (25Hz) tracking of a user specified 2D wireframe and intermittent camera pose parameters to accumulate 3D position information. The 2D tracking framework enables the application of model-based constraints in an intuitive way which interacts naturally with the Kalman...; Tags: 3D, Acquisition, University Of Cambridge, 2D, Mergers & Acquisitions, Corporate Law, Investment, Finance, Business Operations; White papers
Using Calibration in RSSI-Based Location Tracking System: This paper describes an enhancement method for location tracking system based on Received Signal Strength Indicator RSSI-values and Extended Kalman Filter EKF. The enhancement is based on pre-calibration of measurement vectors and individual position block usage in final estimation of the target's position. The EKF and the described enhancement methods...; Tags: Enhancement, LANs, Wireless LANs, Tools & Techniques, Wi-Fi, Wireless, Networking, Management; White papers 2005-03-18
A Communication Architecture for Mobile Wireless Sensor and Actor Networks: In Wireless Sensor and Actor Networks WSANs, the collaborative operation of sensors enables the distributed sensing of a physical phenomenon, while actors collect and process sensor data and perform appropriate actions. In this paper, the coordination and communication problems in WSANs with mobile actors are studied. A hybrid location management...; Tags: Mobile, Network, Sensor, Actor, Wireless, Advertising & Promotion, Marketing; White papers 2006-07-10
Estimation of RTT and Bandwidth for Congestion Control Applications in Communication Networks: Heterogeneous communication networks with their variety of application demands, uncertain time-varying traffic load, and mixture of wired and wireless links pose several challenging problem in modeling and control. This paper focuses on the Round-Trip Time RTT, which is a particularly important variable for efficient end-to-end congestion control, and on bandwidth...; Tags: Estimation, Algorithm, Bandwidth, Network, Congestion, RTT, Engineering, Networking; White papers 2007-08-04
Establish and implement effective security policies: This sample chapter, taken from Web Security Field Guide, presents a way for you to decide what your security goals are and establish, implement, and enforce the security rules that will help you achieve them. The chapter covers the following topics:Justifying SecuritySecurity PoliciesTitle: Web Security Field GuideISBN: 1587050927Published: November 2002Author:...; Tags: security, Web Security Field Guide, Web security, Cisco Systems Inc., security policy, Web; Download resources 2006-04-14
