Summary: This book provides an excellent reference for all professionals working in the area of array signal processing and its applications in wireless communications. Wideband beamforming has advanced with the increasing bandwidth in wireless communications and the development of ultra wideband (UWB) technology. In this book, the authors address the fundamentals and most recent developments in the field of wideband beamforming. The book provides a thorough coverage of the subject including major sub-areas such as sub-band adaptive beamforming, frequency invariant beamforming, blind wideband beamforming, beamforming without temporal processing, and beamforming for multi-path signals. Key Features: Unique book focusing on wideband beamforming Discusses a hot topic coinciding with the increasing bandwidth in wireless communications and the development of UWB technology Addresses the general concept of beamforming including fixed beamformers and adaptive beamformers Covers advanced topics including sub-band adaptive beamforming, frequency invariant beamforming, blind wideband beamforming, beamforming without temporal processing, and beamforming for multi-path signals Includes various design examples and corresponding complexity analyses This book provides a reference for engineers and researchers in wireless communications and signal processing fields. Postgraduate students studying signal processing will also find this book of interest.Summary: Intro -- Wideband Beamforming -- Contents -- About the Series Editors -- Preface -- 1 Introduction -- 1.1 Array Signal Processing -- 1.2 Narrowband Beamforming -- 1.3 Wideband Beamforming -- 1.4 Wideband Beam Steering -- 1.4.1 Beam Steering for Narrowband Arrays -- 1.4.2 Beam Steering for Wideband Arrays -- 1.4.3 A Unified Interpretation -- 1.5 Summary -- 2 Adaptive Wideband Beamforming -- 2.1 Reference Signal-Based Beamformer -- 2.1.1 Least Mean Square Algorithm -- 2.1.2 Normalized Least Mean Square Algorithm -- 2.1.3 Recursive Least Squares Algorithm -- 2.1.4 Comparison of Computational Complexities -- 2.1.5 Frequency-Domain and Subband Adaptive Algorithms -- 2.1.6 Simulations -- 2.2 Linearly Constrained Minimum Variance Beamforming -- 2.2.1 A Simple Formulation of Constraints -- 2.2.2 Optimum Solution to the LCMV Problem -- 2.2.3 Frost's Algorithm for LCMV Beamforming -- 2.2.4 Simulations -- 2.3 Constraints Design for LCMV Beamforming -- 2.3.1 Eigenvector Constraint Design -- 2.3.2 Design Example -- 2.3.3 Application to Wideband DOA Estimation -- 2.4 Generalized Sidelobe Canceller -- 2.4.1 GSC Structure -- 2.4.2 GSC with Tapped Delay-Lines -- 2.4.3 Blocking Matrix Design -- 2.4.4 Simulations -- 2.5 Other Minimum Variance Beamformers -- 2.5.1 Soft Constrained Minimum Variance Beamformer -- 2.5.2 Correlation Constrained Minimum Variance Beamformer -- 2.6 Robust Adaptive Beamforming -- 2.6.1 Spatially Extended Constraints -- 2.6.2 Norm-Restrained Approaches -- 2.7 Summary -- 3 Subband Adaptive Beamforming -- 3.1 Fundamentals of Filter Banks -- 3.1.1 Basic Multirate Operations -- 3.1.2 Perfect Reconstruction Condition for Filter Banks -- 3.1.3 Oversampled Modulated Filter Banks -- 3.2 Subband Adaptive Filtering -- 3.3 General Subband Adaptive Beamforming -- 3.3.1 Reference Signal Based Beamformer -- 3.3.2 Generalized Sidelobe Canceller.PPN: PPN: 808848976Package identifier: Produktsigel: ZDB-26-MYL | ZDB-30-PAD | ZDB-30-PQE | BSZ-30-PQE-K1DLR
