Positioning in Wireless Communications Systems (ePub)

Positioning in Wireless Communications Systems explainsthe principal differences and similarities of wirelesscommunications systems and navigation systems. It discussesscenarios which are critical for dedicated navigation systems suchas the Global Positioning System (GPS) and which motivate the useof positioning based on terrestrial wireless communicationsystems.

The book introduces approaches for determination of parameterswhich are dependent on the position of the mobile terminal and also discusses iterative algorithms to estimate and trackthe position of the mobile terminal. Models for radio propagationand user mobility are important for performance investigations andassessments using computer simulations. Thus, channel and mobilitymodels are explored, especially focussing on critical navigationenvironments like urban or indoor scenarios.

Positioning in Wireless Communications Systems examinesadvanced algorithms such as hybrid data fusion of satellitenavigation and positioning with wireless communications andcooperative positioning among mobile terminals.. The performance ofthe discussed positioning techniques are explored on the basis ofalready existing and operable terrestrial wireless communicationsystems such as GSM, UMTS, or LTE and it is shown how positioningissues are fixed in respective standards.

Written by industry experts working at the cutting edge oftechnological development, the authors are well placed to give anexcellent view on this topic, enabling in-depth coverage of currentdevelopments.
