Journal ArticleDOI
Reproduction of a plane-wave sound field using an array of loudspeakers
D.B. Ward,Thushara D. Abhayapala +1 more
TL;DR: A spherical harmonics analysis is used to derive performance bounds on how well an array of loudspeakers can recreate a three-dimensional (3-D) plane-wave sound field within a spherical region of space.
Proceedings ArticleDOI
Theory and design of high order sound field microphones using spherical microphone array
Thushara D. Abhayapala,D.B. Ward +1 more
TL;DR: Spherical harmonics analysis is used to establish theory and design of a higher order recording system, which comprises an array of small microphones arranged in a spherical configuration and associated signal processing, which has implications to the advancement of future sound field reconstruction systems.
Journal ArticleDOI
Intrinsic Limits of Dimensionality and Richness in Random Multipath Fields
TL;DR: A lower bound on the largest eigenvalue of the Karhunen-Loegraveve (KL) expansion of random multipath fields is established, which quantifies, to some extent, the well-known reduction of multipath richness with reducing the angular power spread of multipATH angular power spectrum.
Journal ArticleDOI
Theory and design of sound field reproduction in reverberant rooms.
TL;DR: A method of sound field reproduction for reverberant environments is developed with an efficient parametrization of the acoustic transfer function over a region of space and reveals the appropriate choices for fundamental design parameters.
Journal ArticleDOI
Error Bounds for Uplink and Downlink 3D Localization in 5G Millimeter Wave Systems
TL;DR: In this article, the uplink and downlink localization limits in terms of 3D position and orientation error bounds for mm-wave multipath channels were analyzed. And the authors carried out a detailed analysis of the dependence of the bounds on different system parameters.
