Update on the German and Australasian Optical Ground Station Networks
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Networks of ground stations designed to transmit and receive at visible and infra‐red wavelengths through the atmosphere offer an opportunity to provide on‐demand, high‐bandwidth, secure communications with spacecraft in Earth orbit and beyond. This work describes the operation and activities of current free space optical communications (FSOC)

Optimal Placement of UAVs for Minimum Outage Probability
IEEE Transactions on Vehicular Technology, 2022 We consider multiple unmanned aerial vehicles (UAVs) serving a density of ground terminals (GTs) as base stations. The objective is to minimize the outage probability of GT-to-UAV transmissions. Optimal placement of UAVs under different UAV altitude constraints and GT densities is studied.

Tradeoff Caching Strategy of the Outage Probability and Fronthaul Usage in a Cloud-RAN [PDF]
IEEE Transactions on Vehicular Technology, 2016 In this paper, a tradeoff content caching strategy is proposed to jointly minimize the cell average outage probability and fronthaul usage in a cloud radio access network. At first, an accurate closed-form expression of the outage probability conditioned

Explaining Microservices' Cascading Failures From Their Logs
Software: Practice and Experience, EarlyView.ABSTRACT Context Identifying the possible root causes of observed failures is crucial in microservice applications, as much as explaining how such possible root failures propagated across the microservices forming an application. This can indeed help pick countermeasures avoiding observed failures to happen again, e.g., by introducing circuit breakers ...

Compound Outage Probability and Capacity of a Class of Fading MIMO Channels with Channel Distribution Uncertainty [PDF]
arXiv, 2011 Outage probability and capacity of a class of block-fading MIMO channels are considered with partial channel distribution information. Specifically, the channel or its distribution are not known but the latter is known to belong to a class of distributions where each member is within a certain distance (uncertainty) from a nominal distribution ...

Outage Analysis on Type I HARQ over Time-Correlated Rayleigh Fading Channels [PDF]
arXiv, 2022 This paper analyzes Type I hybrid automatic repeat request (HARQ) over time-correlated Rayleigh fading channels. Due to the presence of channel time correlation, the analysis is more challenging than the prior analysis in the literature. Outage probability is first derived as a weighted sum of joint CDF of multiple independent Gamma random variables ...

Outage Constrained Robust Secure Transmission for MISO Wiretap Channels [PDF]
, 2013 In this paper we consider the robust secure beamformer design for MISO wiretap channels. Assume that the eavesdroppers' channels are only partially available at the transmitter, we seek to maximize the secrecy rate under the transmit power and secrecy ...
