MMSE-Based MDL Method for Robust Estimation of Number of Sources Without Eigendecomposition
收藏 引用
IEEE TRANSACTIONS ON SIGNAL processing 2009年 第10期57卷 4135-4142页
作者: Huang, Lei Long, Teng Mao, Erke So, H. C. Beijing Inst Technol Dept Elect Engn Beijing 100081 Peoples R China City Univ Hong Kong Dept Elect Engn Kowloon Hong Kong Peoples R China
It is well known that the conventional eigenvalue-based minimum description length (MDL) approach for source number estimation suffers from high computational load and performs optimally only in the presence of spatia... 详细信息

Optimal Sample Complexity for Blind Gain and Phase Calibration
收藏 引用
IEEE TRANSACTIONS ON SIGNAL processing 2016年 第21期64卷 5549-5556页
作者: Li, Yanjun Lee, Kiryung Bresler, Yoram Univ Illinois Coordinated Sci Lab Urbana IL 61801 USA Univ Illinois Dept Elect & Comp Engn Urbana IL 61801 USA Georgia Inst Technol Sch Elect & Comp Engn Atlanta GA 30332 USA
Blind gain and phase calibration (BGPC) is a structured bilinear inverse problem, which arises in many applications, including inverse rendering in computational relighting (albedo estimation with unknown lighting), b... 详细信息

Identifiability in Bilinear Inverse Problems With Applications to Subspace or Sparsity-Constrained Blind Gain and Phase Calibration
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2017年 第2期63卷 822-842页
作者: Li, Yanjun Lee, Kiryung Bresler, Yoram Univ Illinois Dept Elect & Comp Engn Coordinated Sci Lab Champaign IL 61801 USA Georgia Inst Technol Sch Elect & Comp Engn Atlanta GA 30332 USA
Bilinear inverse problems (BIPs), the resolution of two vectors given their image under a bilinear mapping, arise in many applications. Without further constraints, BIPs are usually ill-posed. In practice, the propert... 详细信息

A new subspace identification algorithm for high-resolution DOA estimation
收藏 引用
IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION 2002年 第10期50卷 1382-1390页
作者: McCloud, ML Scharf, LL Magis Networks Inc San Diego CA 92130 USA Colorado State Univ Ft Collins CO 80523 USA
In this paper, we propose a new direction of arrival (DOA) estimator for sensor-array processing. The estimator is based on a linear algebraic connection between the standard subspace model of the array correlation ma... 详细信息

Efficient Dipole Parameter Estimation in EEG Systems With Near-ML Performance
收藏 引用
IEEE TRANSACTIONS ON BIOMEDICAL ENGINEERING 2012年 第5期59卷 1339-1348页
作者: Wu, Shun Chi Swindlehurst, A. Lee Wang, Po T. Nenadic, Zoran Univ Calif Irvine Dept Elect Engn & Comp Sci Irvine CA 92697 USA Univ Calif Irvine Dept Biomed Engn Irvine CA 92697 USA
Source signals that have strong temporal correlation can pose a challenge for high-resolution EEG source localization algorithms. In this paper, we present two methods that are able to accurately locate highly correla... 详细信息

A low-complexity estimator for incoherently distributed sources with narrow or wide spread angles
收藏 引用
SIGNAL processing 2007年 第5期87卷 1058-1065页
作者: Li, Gang Xu, Jia Peng, Ying-Ning Xia, Xiang-Gen Tsinghua Univ Dept Elect Engn Beijing 100084 Peoples R China Radar Acad Airforce Wuhan 430010 Peoples R China Univ Delaware Dept Elect & Comp Engn Newark DE 19716 USA
In this paper, a concept of contrast of eigenvalues (COE) is introduced to describe the diversity of the eigenvalues of signal covariance matrix. Based on the COE, a novel algorithm is proposed to estimate the central... 详细信息

A sparse signal reconstruction perspective for source localization with sensor arrays
收藏 引用
IEEE TRANSACTIONS ON SIGNAL processing 2005年 第8期53卷 3010-3022页
作者: Malioutov, D Çetin, M Willsky, AS MIT Dept Elect Engn & Comp Sci Cambridge MA 02139 USA
We present a source localization method based on a sparse representation of sensor measurements with an overcomplete basis composed of samples from the array manifold. We enforce sparsity by imposing penalties based o... 详细信息

Design of chemical sensor arrays for monitoring disposal sites on the ocean floor
收藏 引用
IEEE JOURNAL OF OCEANIC ENGINEERING 1998年 第4期23卷 334-343页
作者: Jeremic, A Nehorai, A Univ Illinois Dept Elect Engn & Comp Sci Chicago IL 60607 USA
We develop methods for automatic environmental monitoring of disposal sites on the deep ocean door using chemical sensor arrays and statistical hypothesis testing. Such sites have been proposed to relocate dredge mate... 详细信息

Blind identification of FIR MIMO channels by decorrelating subchannels
收藏 引用
IEEE TRANSACTIONS ON SIGNAL processing 2003年 第5期51卷 1143-1155页
作者: Hua, YB An, SJ Xiang, Y Univ Calif Riverside Dept Elect Engn Riverside CA 92521 USA Univ Melbourne Dept Elect & Elect Engn Parkville Vic 3010 Australia
We study blind identification and equalization of finite impulse response (FIR) and multi-input and multi-output (MIMO) channels driven by colored signals. We first show a sufficient condition for an FIR MIMO channel ... 详细信息
