Lower bounds on the estimation performance in low complexity quantize-and-forward cooperative systems [PDF]
, 2015 Cooperative communication can effectively mitigate the effects of multipath propagation fading by using relay channels to provide spatial diversity. A relaying scheme suitable for half-duplex devices is the quantize-and-forward (QF) protocol, in which ...

Random arrays for source parameter estimation
Electronics Letters, 1976 Phase measurements at the elements of a highly thinned, large-aperture random array can be used to efficiently estimate the parameters of a distant source. The theory for this is developed, and an illustrative computer stimulation example is given.

A novel quantize-and-forward cooperative system : channel parameter estimation techniques [PDF]
, 2010 The Quantize and Forward cooperative communication protocol improves the reliability of data transmission by allowing a relay to forward to the destination a quantized version of the signal received from the source.

Emitting electrons and source activity in Markarian 501
, 2012 We study the variation of the broad-band spectral energy distribution (SED) of the BL Lac object Mrk 501 as a function of source activity, from quiescent to flaring. Through chi-square-minimization we model eight simultaneous SED datasets with a one-zone

Modeling source parameters of quasi-periodic tremor
Volcanica, 2020 Modeling harmonic tremor recorded at volcanoes is an essential practice in improving eruption forecasting methods and warning systems. We model the conduit dynamics of quasi-periodic tremor (chugging) recorded at Karymsky, Tungurahua, and Fuego volcanoes

Laser beam shaping for enhanced Zero-Group Velocity Lamb modes generation
, 2016 Optimization of Lamb modes induced by laser can be achieved by adjusting the spatial source distribution to the mode wavelength ($\lambda$). The excitability of Zero-Group Velocity (ZGV) resonances in isotropic plates is investigated both theoretically ...

Source parameters of the M 6.5 Skyros Island (North Aegean Sea) earthquake of July 26, 2001
Annals of Geophysics, 2002 Teleseismic body wave modelling, time domain moment tensor inversion of regional waveforms and spectral analysis of the far-field P-wave pulses are used to derive the source parameters of the July 26, 2001 Skyros earthquake (M 6.5).

Determination of density of states of thin high-$T_c$ films by FET type microstructures
, 2006 A simple electronic experiment with a field effect transistor type microstructure is suggested. The thin superconductor layer is the source-drain channel of the layered structure where an AC current is applied.
