Book Synopsis Broadband Array Processing by : Shefeng Yan

Download or read book Broadband Array Processing written by Shefeng Yan. This book was released on 2019-05-06. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the background and technology of array signal modeling. It presents the concept and formulation of beamformers and discusses several commonly used array performance measures. It also introduces two traditional types of beamformers: delay-and-sum and optimum beamformers. Chapter 1 includes background information on array processing, while Chapters 2 and 3 discuss the DFT-based frequency-domain implementation of a broadband beamformer and the design of subband beamformers for frequency-domain broadband beamformers. Chapter 4 presents the FIR-based, time-domain implementation of the broadband beamformer, where the FIR beamformer is designed by separately designing the subband beamformers and the corresponding FIR filters. The techniques for optimal design of the FIR beamformer are developed in Chapter 5, and Chapters 6 and 7 focus on the modal beamforming problem for circular arrays for the frequency-domain modal beamformer and the time-domain modal beamformer. Lastly, the final chapters present frequency-domain and time-domain modal beamformers for spherical arrays.

Book excerpt: This document contains observations concerning the analysis of broadband processes as applied to passive spatial array processing. The analysis is intended to be applicable to general acoustic propagation environments. In section 1.0, we use a linear systems model of the propagation environment in our analysis of the spatial/spectral estimation problem. We show how this view also might be used in the moving source problem. We also briefly discuss correlations between Fourier coefficients at different frequencies. In section 2.0, we look at approaches to broadband array processing that take advantage of the frequency extent of the source process in estimating the spatial spectrum.

Book Synopsis Microphone Array Signal Processing by : Jacob Benesty

Download or read book Microphone Array Signal Processing written by Jacob Benesty. This book was released on 2008-03-11. Available in PDF, EPUB and Kindle. Book excerpt: In the past few years we have written and edited several books in the area of acousticandspeechsignalprocessing. Thereasonbehindthisendeavoristhat there were almost no books available in the literature when we ?rst started while there was (and still is) a real need to publish manuscripts summarizing the most useful ideas, concepts, results, and state-of-the-art algorithms in this important area of research. According to all the feedback we have received so far, we can say that we were right in doing this. Recently, several other researchers have followed us in this journey and have published interesting books with their own visions and perspectives. The idea of writing a book on Microphone Array Signal Processing comes from discussions we have had with many colleagues and friends. As a c- sequence of these discussions, we came up with the conclusion that, again, there is an urgent need for a monograph that carefully explains the theory and implementation of microphone arrays. While there are many manuscripts on antenna arrays from a narrowband perspective (narrowband signals and narrowband processing), the literature is quite scarce when it comes to s- sor arrays explained from a truly broadband perspective. Many algorithms for speech applications were simply borrowed from narrowband antenna - rays. However, a direct application of narrowband ideas to broadband speech processing may not be necessarily appropriate and can lead to many m- understandings.
