Hybrid Analog-Digital Precoding for Interference Exploitation [PDF]

open access: yes, 2018
We study the multi-user massive multiple-input-single-output (MISO) and focus on the downlink systems where the base station (BS) employs hybrid analog-digital precoding with low-cost 1-bit digital-to-analog converters (DACs). In this paper, we propose a

Quantum geometry, logic and probability

open access: yesZagadnienia Filozoficzne w Nauce, 2020
Quantum geometry on a discrete set means a directed graph with a weight associated to each arrow defining the quantum metric. However, these ‘lattice spacing’ weights do not have to be independent of the direction of the arrow.

Writing Reusable Digital Geometry Algorithms in a Generic Image Processing Framework

open access: yes, 2012
Digital Geometry software should reflect the generality of the underlying mathe- matics: mapping the latter to the former requires genericity. By designing generic solutions, one can effectively reuse digital geometry data structures and algorithms.

Digital Holography at Shot Noise Level [PDF]

open access: yes, 2010
By a proper arrangement of a digital holography setup, that combines off-axis geometry with phase-shifting recording conditions, it is possible to reach the theoretical shot noise limit, in real-time experiments.We studied this limit, and we show that it
