TL;DR: The International LOFAR Telescope (ILT) as mentioned in this paper is a new-generation radio interferometer constructed in the north of the Netherlands and across europe, which covers the largely unexplored low frequency range from 10-240 MHz and provides a number of unique observing capabilities.
Journal ArticleDOI
An analytical constant modulus algorithm
A. van Veen,Arogyaswami Paulraj +1 more
TL;DR: It is shown that the underlying constant modulus factorization problem is, in fact, a generalized eigenvalue problem, and may be solved via a simultaneous diagonalization of a set of matrices.
Journal ArticleDOI
Analog Beamforming in MIMO Communications With Phase Shift Networks and Online Channel Estimation
Vijay Venkateswaran,A. van Veen +1 more
TL;DR: This paper considers the design of the analog and digital beamforming coefficients, for the case of narrowband signals, and proposes the optimal analog beamformer to minimize the mean squared error between the desired user and its receiver estimate.
Proceedings ArticleDOI
Analysis of positron profiling data by means of ‘‘VEPFIT’’
TL;DR: In this paper, the authors presented a semi-linear fitting procedure for the Doppler broadening parameter S and the positronium fraction F vs the energy of the incident positrons.
Journal ArticleDOI
Subspace-based signal analysis using singular value decomposition
TL;DR: A unified approach is presented to the related problems of recovering signal parameters from noisy observations and identifying linear system model parameters from observed input/output signals, both using singular value decomposition (SVD) techniques.
