Analysis of Load Balancing and Interference Management in Heterogeneous Cellular Networks
IEEE Access, 2017 To meet the current cellular capacity demands, proactive offloading is required in heterogeneous cellular networks (HetCNets) comprising of different tiers of base stations (BSs), e.g., small-cell BSs (sBSs) and conventional macro-cell BSs (mBSs).

On the performance of densified DVB-H single frequency networks [PDF]
, 2006 The broadcasting of TV programmes to mobile phones can be enabled by the newly developed technology called Digital Video Broadcasting-Handheld (DVB-H). Because of the scarcity and cost of frequency resources, frequency reuse needs to be considered when ...

Coverage Analysis for UAV-Assisted Cellular Networks in Rural Areas
IEEE Open Journal of Vehicular Technology, 2021 Despite enhancement in rural areas is one of the main requirements in next generations of wireless networks (i.e., 5G and 6G), the low expected profit prevents telecommunication providers from investing in such sparsely populated areas.

Impact of 3D Antenna Radiation Pattern on Heterogeneous Cellular Networks
IEEE Access, 2022 Heterogeneous cellular networks (HCNs) play a significant role in 5G networks, but have mainly been modeled and analyzed on a two-dimensional (2D) plane.

Jackknife Empirical Likelihood Inference for the Variance Residual Life Function
Revstat Statistical Journal, 2021 In life testing situations, the residual life time of a component which has survived t units of time is Xt = X −t|X > t. In this paper, we give a central limit theorem result for the estimator of Var(Xt), the variance residual life(VRL) function.

On the meaning of coverage probabilities
Metrologia, 2009 It has been argued that the probability associated with a coverage interval calculated following the procedure proposed in Supplement 1 to the GUM should be about equal to the proportion of independent intervals reckoned over time that contain the measurand (Willink 2006 Metrologia 43 L39–42, Hall 2008 Metrologia 45 L5–8, Possolo et al 2009 Metrologia ...

A Penalized Likelihood Approach to Parameter Estimation with Integral Reliability Constraints
Entropy, 2015 Stress-strength reliability problems arise frequently in applied statistics and related fields. Often they involve two independent and possibly small samples of measurements on strength and breakdown pressures (stress).

Coverage Probability of Cell-Free Massive MIMO Systems [PDF]
2020 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).
