Reihe: Wireless Communications and Mobile Computing

This book provides an excellent reference for all professionalsworking in the area of array signal processing and its applicationsin wireless communications.
Wideband beamforming has advanced with the increasing bandwidthin wireless communications and the development of ultra wideband(UWB) technology.
In this book, the authors address the fundamentals and mostrecent developments in the field of wideband beamforming. The bookprovides a thorough coverage of the subject including majorsub-areas such as sub-band adaptive beamforming, frequencyinvariant beamforming, blind wideband beamforming, beamformingwithout temporal processing, and beamforming for multi-pathsignals.
Key Features:
* Unique book focusing on wideband beamforming
* Discusses a hot topic coinciding with the increasing bandwidthin wireless communications and the development of UWBtechnology
* Addresses the general concept of beamforming including fixedbeamformers and adaptive beamformers
* Covers advanced topics including sub-band adaptive beamforming,frequency invariant beamforming, blind wideband beamforming,beamforming without temporal processing, and beamforming formulti-path signals
* Includes various design examples and corresponding complexityanalyses
This book provides a reference for engineers and researchers inwireless communications and signal processing fields. Postgraduatestudents studying signal processing will also find this book ofinterest.

Dr. Wei Liu, University of Sheffield, UK
Dr Liu received his B.Sc. in Space Physics (1996) and L.L.B in Intellectual Property Law (1997) from Peking University, China; M.Phil. in Filter Banks and Wavelets from the Department of Electrical and Electronic Engineering, University of Hong Kong (2001); PhD in Digital Beamforming from the Communications Research Group, School of Electronics and Computer Science, University of Southampton (2003). He then worked as a postdoc in the same group and later in the Communications and Signal Processing Group, Department of Electrical and Electronic Engineering, Imperial College London, where he moved to the area of blind source separation. In September 2005, Dr Liu joined the Communications Research Group, Department of Electronic and Electrical Engineering, University of Sheffield, as a lecturer.

Dr. Stephan Weiss, University of Strathclyde, Scotland
Dr Weiss received the degree of Diplom-Ingenieur in Electronic & Electrical Engineering from the University of Erlangen-Nürnberg in 1995, and the PhD in the same subject from the University of Strathclyde in 1998. Interrupted by a leave in 1996/97 as a visiting scholar at the Signal and Image Processing Institute, University of Southern California, he was a research student in the Signal Processing Division, University of Strathclyde. He held a visiting lectureship in the EEE Department at Strathclyde in 1998/99, and joined the Communications Research Group of the Electronics and Computer Science Department at the University of Southampton as a lecturer in 1999. He was promoted to a senior lecturership at University of Strathclyde in 2003.
