Image formation in synthetic aperture radio telescopes
Ronny Levanda, Amir Leshem
Next generation radio telescopes will be much larger, more sensitive, have much larger observation bandwidth and will be capable of pointing multiple beams simultaneously. Obtainin…
Adaptive selective sidelobe canceller beamformer with applications in radio astronomy
Ronny Levanda, Amir Leshem
We propose a new algorithm, for parameter estimation that is applicable to imaging using moving and synthetic aperture arrays. The new method results in higher resolution and more…
Weighted Max-Min Resource Allocation for Frequency Selective Channels
Ephi Zehavi, Amir Leshem, Ronny Levanda +1
In this paper, we discuss the computation of weighted max-min rate allocation using joint TDM/FDM strategies under a PSD mask constraint. We show that the weighted max-min solution…
Competitive Spectrum Management with Incomplete Information
Yair Noam, Amir Leshem, Hagit Messer
This paper studies an interference interaction (game) between selfish and independent wireless communication systems in the same frequency band. Each system (player) has incomplete…
MIMO Detection for High-Order QAM Based on a Gaussian Tree Approximation
Jacobb Goldberger, Amir Leshem
This paper proposes a new detection algorithm for MIMO communication systems employing high order QAM constellations. The factor graph that corresponds to this problem is very loop…
