Positioning in Wireless Communications Systems

Positioning in Wireless Communications Systems explains the principal differences and similarities of wireless communications systems and navigation systems. It discusses scenarios that are critical for dedicated navigation systems such as the Global Positioning System (GPS), and which motivate the use of positioning based on terrestrial wireless communication systems.

The book introduces approaches for determining parameters that are dependent on the position of the mobile terminal and also discusses iterative algorithms to estimate and track positions. Models for radio propagation and user mobility are important for performance investigations and assessments using computer simulations. Thus, channel and mobility models are explored, particularly focusing on critical navigation environments such as urban and indoor scenarios.

Positioning in Wireless Communications Systems examines advanced algorithms such as hybrid data fusion of satellite navigation, and positioning with wireless communications and cooperative positioning among mobile terminals. The performance of the discussed positioning techniques are explored on the basis of already existing and operable terrestrial wireless communication systems such as GSM, UMTS, or LTE and how positioning issues are fixed in respective standards is shown.

Written by industry experts working at the cutting edge of technological development, the authors are well-placed to give an excellent viewpoint on this topic, enabling in-depth coverage of current developments.
