Coverage Analysis of LEO Satellite Downlink Networks: Orbit Geometry Dependent Approach [PDF]
arXiv, 2022 The low-earth-orbit (LEO) satellite network with mega-constellations can provide global coverage while supporting the high-data rates. The coverage performance of such a network is highly dependent on orbit geometry parameters, including satellite altitude and inclination angle. Traditionally, simulation-based coverage analysis dominates because of the

Bootstrap prediction intervals with asymptotic conditional validity and unconditional guarantees [PDF]
arXiv, 2020 It can be argued that optimal prediction should take into account all available data. Therefore, to evaluate a prediction interval's performance one should employ conditional coverage probability, conditioning on all available observations. Focusing on a linear model, we derive the asymptotic distribution of the difference between the conditional ...

On Inference about Tilt Parameter in Marshall-Olkin Family of Distributions
Journal of Statistical Theory and Applications (JSTA), 2018 Marshall and Olkin [Biometrika199784641652] introduced a method for constructing a new distribution by adding a new parameter, called tilt parameter, to a parent distribution.

On Coverage Probability in Uplink NOMA With Instantaneous Signal Power-Based User Ranking [PDF]
arXiv, 2019 In uplink non-orthogonal multiple access (NOMA) networks, the order of decoding at the base station (BS) depends on the received instantaneous signal powers (ISPs). Therefore, the signal-to-interference-plus-noise ratio (SINR) coverage probability for an uplink NOMA user should be calculated using the ISP-based ranking of the users.

Prediction Limits for Poisson INAR(1) Process
Journal of Mathematical and Fundamental Sciences, 2015 We discuss the problem of deriving an estimative prediction limit as well as a simulation-based improved prediction limit for a future realization from the stationary, first-order Poisson INAR(1) process.

Efficient Deployment of Multiple Unmanned Aerial Vehicles for Optimal Wireless Coverage [PDF]
, 2016 In this paper, the efficient deployment of multiple unmanned aerial vehicles (UAVs) with directional antennas acting as wireless base stations that provide coverage for ground users is analyzed. First, the downlink coverage probability for UAVs as a function of the altitude and the antenna gain is derived.
