10th ieee sensor array and multichannel signal processing workshop (SAM)
作者: Diaz-Guerra, David Beltran, Jose R. Univ Zaragoza Dept Elect Engn & Commun Zaragoza Spain
The Steered Response Power with phase transform (SRP-PHAT) is one of the most employed techniques for Direction of Arrival (DOA) estimation with microphone arrays due its robustness against acoustical conditions as re... 详细信息

作者: Zhang, Yimin D. Chowdhury, Md Waqeeb T. S. Temple Univ Dept Elect & Comp Engn Philadelphia PA 19122 USA
In this paper, we propose high-resolution target direction-of-arrival (DOA) estimation using frequency-switching sparse arrays which implement multi-frequency sparse arrays in a low-complexity manner. Unlike multi-fre... 详细信息

作者: Yang, Bowen Molu, Mehdi M. Zhang, Lei Univ Glasgow Sch Engn Glasgow G12 8QQ Lanark Scotland SCSC Cambridge CB4 0DS England
One of the fundamental problems for hybrid beamformer design in MIMO systems is that, in Singular-Value-Decomposition (SVD) based beamforming, the analog beamformer is limited to constant modulus. In order to solve th... 详细信息
