3rd ieee sensor array and multichannel signal processing workshop
作者: Mysore, N Bajcsy, J McGill Univ Dept Elect & Comp Engn Montreal PQ H3A 2A7 Canada
We consider the problem of achieving high data rates for uplink transmission on multi-input, multi-output (MIMO) channels. We propose a soft decision space-time detection scheme of linear complexity in a turbo-coded a... 详细信息

3rd ieee sensor array and multichannel signal processing workshop
作者: Comon, P Rajih, M I3S Lab F-06903 Sophia Antipolis France
This paper is devoted to under-determined linear mixtures of independent random variables (i.e. with more inputs than outputs). Blind identifiability of general under-determined mixtures is first discussed, and the ma... 详细信息

3rd ieee sensor array and multichannel signal processing workshop
作者: Kikuchi, S Tsuji, H Sano, A Keio Univ Sch Integrated Design Engn Yokohama Kanagawa 2238522 Japan
We propose a novel direction-of-arrival (DOA) estimation method, which uses sensors of the receiving array, for spatially non-symmetric distributed sources characterized by multipath fading. Specifically, the probabil... 详细信息

3rd ieee sensor array and multichannel signal processing workshop
作者: Abad, A Hernando, J Univ Politecn Catalunya TALP Res Ctr Dept Signal Theory & Commun Barcelona Spain
Speech is dramatically degraded when a distant microphone is used in real environments. One of the possible solutions is to use a microphone array to improve the quality of the recorded speech signal. In this paper we... 详细信息

作者: Loughlin, P Cohen, L Univ Pittsburgh Dept Elect Engn Pittsburgh PA 15261 USA
We discuss dispersive wave propagation and show that the Wigner distribution is a powerful approach because it simplifies the issues immensely. We show that the spatial time-frequency array processing formulation of A... 详细信息

3rd ieee sensor array and multichannel signal processing workshop
作者: Pham, T Scherber, DS Papadopoulos, HC USA Res Lab Acoust Signal Proc Branch Adelphi MD 20783 USA
In this paper, we develop and evaluate distributed implementations of source localization estimators from energy-based measurements obtained via an ad-hoc network of acoustic sensors. The distributed locally construct... 详细信息

作者: Himed, B Kim, K Zhang, YH Hajjari, A USAF Res Lab SNRT Rome NY 13441 USA
This paper presents a new methodology for airborne wideband space-time adaptive processing (W-STAP) radar systems. In W-STAP, the wideband target signal is first decomposed into a series of narrowband signals. This is... 详细信息

作者: Mizumachi, M Nakamura, S ATR Spoken Language Translat Res Labs Keihanna Sci City Kyoto 6190288 Japan
This paper describes the problem caused by near-field sound sources. Formerly, the authors proposed a 2-ch passive subtractive beamformer with a single sharp notch for noise reduction. It is obvious that the single sh... 详细信息
