An Experimental Comparison of Radio Transceiver and Transceiver-Free Localization Methods

An Experimental Comparison of Radio Transceiver and Transceiver-Free Localization Methods

This paper presents an experimental performance assessment for localization systems using received signal strength (RSS) measurements from a wireless sensor network. In this experimental study, we compare two types of model-based localization methods: transceiver-based localization, which locates objects using RSS from transmitters to receivers at known locations; and transceiver-free localizat...

A Largely Reconfigurable Impulse Radio UWB Transceiver

Measurement and Computational Modeling of Radio-Frequency Electromagnetic Power Density Around GSM Base Transceiver Station Antennas

Evaluating the power densities emitted by GSM1800 and GSM900 BTS antennas isconducted via two methods. Measurements are carried out in half a square meter grids around twoantennas. CST Microwave STUDIO software is employed to estimate the power densities in order fordetailed antenna and tower modeling and simulation of power density. Finally, measurements obtainedfrom computational and experime...

An experimental comparison of localization methods continued

Localization is one of the fundamental problems in mobile robot navigation. Past experiments show that in general grid-based Markov localization is more robust than Kalman filtering while the latter can be more accurate than the former. Recently new methods for localization employing particle filters became popular. In this paper we compare different localization methods using Kalman filtering,...

An experimental comparison of localization methods

Localization is the process of updating the pose of a robot in an environment, based on sensor readings. In this experimental study, we compare two recent methods for localization of indoor mobile robots: Markov localization, which uses a probability distribution across a grid of robot poses; and scan matching, which uses Kalman filtering techniques based on matching sensor scans. Both these te...
