Antennas and Propagation for Wireless Communication Systems, 2/e (Hardcover)
內容描述
Description
Antennas and propagation are of
fundamental importance to the coverage, capacity and quality of all wireless
communication systems. This book provides a solid grounding in antennas and
propagation, covering terrestrial and satellite radio systems in both mobile
and fixed contexts. Building on the highly successful first edition, this
fully updated text features significant new material and brand new exercises
and supplementary materials to support course tutors. A vital source of
information for practising and aspiring wireless communication engineers as
well as for students at postgraduate and senior undergraduate levels, this
book provides a fundamental grounding in the principles of antennas and
propagation without excessive recourse to mathematics. It also equips the
reader with practical prediction techniques for the design and analysis of a
very wide range of common wireless communication systems.
Including:
Overview of the fundamental electromagnetic principles underlying
propagation and antennas.
Basic concepts of antennas and their application to specific wireless
systems.
Propagation measurement, modelling and prediction for fixed links,
macrocells, microcells, picocells and megacells
Narrowband and wideband channel modelling and the effect of the channel
on communication system performance.
Methods that overcome and transform channel impairments to enhance
performance using diversity, adaptive antennas and equalisers.
Key second edition updates:
New chapters on Antennas for Mobile Systems and Channel Measurements for
Mobile Radio Systems.
Coverage of new technologies, including MIMO antenna systems, Ultra
Wideband (UWB) and the OFDM technology used in Wi-Fi and WiMax systems.
Many new propagation models for macrocells, microcells and picocells.
Fully revised and expanded end-of-chapter exercises.
Solutions manual and presentation slides available online for course
tutors.
