Enhanced Blind Calibration of Uniform Linear Arrays with One-Bit Quantization by Kullback-Leibler Divergence Covariance Fitting
Amir Weiss, Arie Yeredor
One-bit quantization has recently become an attractive option for data acquisition in cutting edge applications, due to the increasing demand for low power and higher sampling rate…
Non-Iterative Blind Calibration of Nested Arrays with Asymptotically Optimal Weighting
Amir Weiss, Arie Yeredor
Blind calibration of sensors arrays (without using calibration signals) is an important, yet challenging problem in array processing. While many methods have been proposed for "cla…
One-Bit Direct Position Determination of Narrowband Gaussian Signals
Amir Weiss, Gregory W. Wornell
One of the main drawbacks of the well-known Direct Position Determination (DPD) method is the requirement that raw signal data be transferred to a common processor. It would theref…
Iterative Symbol Recovery For Power Efficient DC Biased Optical OFDM Systems
Amir Weiss, Arie Yeredor, Mark Shtaif
Orthogonal frequency division multiplexing (OFDM) has proven itself as an effective multi-carrier digital communication technique. In recent years the interest in optical OFDM has…
The Extended "Sequentially Drilled" Joint Congruence Transformation and its Application in Gaussian Independent Vector Analysis
Amir Weiss, Arie Yeredor, Sher Ali Cheema +1
Independent Vector Analysis (IVA) has emerged in recent years as an extension of Independent Component Analysis (ICA) into multiple sets of mixtures, where the source signals in ea…
Performance Analysis of the Gaussian Quasi-Maximum Likelihood Approach for Independent Vector Analysis
Amir Weiss, Sher Ali Cheema, Martin Haardt +1
Maximum Likelihood (ML) estimation requires precise knowledge of the underlying statistical model. In Quasi ML (QML), a presumed model is used as a substitute to the (unknown) true…
Blind Determination of the Number of Sources Using Distance Correlation
Amir Weiss, Arie Yeredor
A novel blind estimate of the number of sources from noisy, linear mixtures is proposed. Based on Székely et al.'s distance correlation measure, we define the Sources' Dependency C…
Asymptotically Optimal Blind Calibration of Uniform Linear Sensor Arrays for Narrowband Gaussian Signals
Amir Weiss, Arie Yeredor
An asymptotically optimal blind calibration scheme of uniform linear arrays for narrowband Gaussian signals is proposed. Rather than taking the direct Maximum Likelihood (ML) appro…
Blind Direction-of-Arrival Estimation in Acoustic Vector-Sensor Arrays via Tensor Decomposition and Kullback-Leibler Divergence Covariance Fitting
Amir Weiss
A blind Direction-of-Arrivals (DOAs) estimate of narrowband signals for Acoustic Vector-Sensor (AVS) arrays is proposed. Building upon the special structure of the signal measured…
