Stochastic Geometry-Based Modeling and Analysis of Citizens Broadband Radio Service System

open access: yesIEEE Access, 2017
In this paper, we model and analyze a cellular network that operates in the licensed band of the 3.5-GHz spectrum and consists of a licensed and an unlicensed operator.

Modeling the conformality of atomic layer deposition: the effect of sticking probability [PDF]

open access: yes, 2009
The key advantage of atomic layer deposition (ALD) is undoubtedly the excellent step coverage, which allows for conformal deposition of thin films in high-aspect-ratio structures. In this paper, a model is proposed to predict the deposited film thickness

Worst-case User Analysis in Poisson Voronoi Cells [PDF]

open access: yes, 2013
In this letter, we focus on the performance of a worst-case mobile user (MU) in the downlink cellular network. We derive the coverage probability and the spectral efficiency of the worst-case MU using stochastic geometry. Through analytical and numerical

Towards a Realistic Assessment of Multiple Antenna HCNs: Residual Additive Transceiver Hardware Impairments and Channel Aging [PDF]

open access: yes, 1947
Given the critical dependence of broadcast channels by the accuracy of channel state information at the transmitter (CSIT), we develop a general downlink model with zero-forcing (ZF) precoding, applied in realistic heterogeneous cellular systems with ...

Sky coverage modeling for the whole sky for laser guide star multiconjugate adaptive optics [PDF]

open access: yes, 2012
The scientific productivity of laser guide star adaptive optics systems strongly depends on the sky coverage, which describes the probability of finding natural guide stars for the tip/tilt wavefront sensor(s) to achieve a certain performance.

Prediction Intervals of the Record-Values Process

open access: yesRevstat Statistical Journal, 2019
In this paper, exact prediction intervals of the record-values process are constructed. The record-values process model, may be considered as the collection of record-values with integer or non-integer indices.

Coverage Probability of Cell-Free Massive MIMO Systems [PDF]

open access: yes2020 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom), 2020
Despite that ongoing and future networks become denser and increasingly irregular, prior works in the area of cell-free (CF) massive multiple-input-multiple-output (mMIMO) systems relied on the strong assumption of uniformly distributed access points (APs).

User-Centric Interference Nulling in Downlink Multi-Antenna Heterogeneous Networks

open access: yes, 2016
In heterogeneous networks (HetNets), strong interference due to spectrum reuse affects each user's signal-to-interference ratio (SIR), and hence is one limiting factor of network performance. In this paper, we propose a user-centric interference nulling (

Better Confidence Intervals for a Binomial Proportion

open access: yesCommunications, 2010
Interval estimation of a binomial proportion is one of the basic problems in statistics. In technical practice a binomial proportion is often used in statistical quality control.
