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.
