Unified bit-based probabilistic data association aided MIMO detection for high-order QAM constellations [PDF]
, 2011 A unified Bit-based Probabilistic Data Association (B-PDA) detection approach is proposed for Multiple-Input Multiple-Output (MIMO) systems employing high-order rectangular Quadrature Amplitude Modulation (QAM).

On the effects of rough ground and atmospheric absorption on aircraft noise
Noise Mapping, 2022 The noise received from an aircraft is modified by atmospheric attenuation and reflections from the ground. The interference of direct and reflected waves is simplest for a flat ground, whereas multiple reflections can occur for rough ground or ...

Single Boson Images Via an Extended Holstein Primakoff Mapping [PDF]
, 1999 The Holstein-Primakoff mapping for pairs of bosons is extended in order to accommodate single boson mapping. The proposed extension allows a variety of applications and especially puts the formalism at finite temperature on firm grounds.

Noise pollution in rail transport. Case study: Baghdad subway
Noise Mapping, 2022 Noise pollution is one of the environmental factors that severely threaten humans’ mental, emotional, and physical health. One of the most significant sources of this pollution is the noise generated by traffic and urban transportation, mainly the urban ...

Normal subgroups of mapping class groups and the metaconjecture of Ivanov [PDF]
, 2018 We prove that if a normal subgroup of the extended mapping class group of a closed surface has an element of sufficiently small support then its automorphism group and abstract commensurator group are both isomorphic to the extended mapping class group ...

DReAM: Dynamic Re-arrangement of Address Mapping to Improve the Performance of DRAMs
, 2015 The initial location of data in DRAMs is determined and controlled by the 'address-mapping' and even modern memory controllers use a fixed and run-time-agnostic address mapping.
