Performance Analysis of User Pairing in Cooperative NOMA Networks
IEEE Access, 2018 In this paper, we study the coverage probability and average data rate of user pairing in cooperative non-orthogonal multiple access (NOMA) networks. With fixed locations of the source and typical user, the candidate users for pairing follow homogeneous ...

Geometric theory of (extended) time-reversal symmetries in stochastic processes: I. Finite dimension [PDF]
Journal of Statistical Mechanics: Theory and ExperimentIn this article, we analyze three classes of time-reversal of a Markov process with Gaussian noise on a manifold. We first unveil a commutativity constraint for the most general of these time-reversals to be well defined.

Nuts and Bolts of a Realistic Stochastic Geometric Analysis of mmWave HetNets: Hardware Impairments and Channel Aging [PDF]
IEEE Transactions on Vehicular Technology, 2019 Motivated by heterogeneous network (HetNet) design in improving coverage and by millimeter-wave (mmWave) transmission offering an abundance of extra spectrum, we present a general analytical framework shedding light on the downlink of realistic mmWave ...

Research on the spatial characterization of a 3D UAV air-to-ground channel model
Tongxin xuebao, 2020 To cope with the problem that the distribution assumptions of arrival angle and departure angle in existing geometry-based stochastic modeling (GBSM) for the unmanned aerial vehicle (UAV) air-to-ground (A2G) channel are too ideal to describe the spatial ...

Stochastic Geometric Coverage Analysis in mmWave Cellular Networks with a Realistic Channel Model [PDF]
Global Communications Conference, 2017 Millimeter-wave (mmWave) bands have been attracting growing attention as a possible candidate for next- generation cellular networks, since the available spectrum is orders of magnitude larger than in current cellular allocations.

Stochastic approach for radionuclides quantification
EPJ Web of Conferences, 2018 Gamma spectrometry is a passive non-destructive assay used to quantify radionuclides present in more or less complex objects. Basic methods using empirical calibration with a standard in order to quantify the activity of nuclear materials by determining ...

The scaling limit of Poisson-driven order statistics with applications in geometric probability [PDF]
, 2012 Let ηt be a Poisson point process of intensity t≥1 on some state space Y and let f be a non-negative symmetric function on Yk for some k≥1. Applying f to all k-tuples of distinct points of ηt generates a point process ξt on the positive real half-axis ...

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization
Advanced Engineering Materials, EarlyView.Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...
