Interference and SINR coverage in spatial non-slotted Aloha networks [PDF]
Annales des t\'el\'ecommunications- Annals of telecommunications,
2015, 70 (7), pp.345-358, 2014 In this paper we propose two analytically tractable stochastic-geometric models of interference in ad-hoc networks using pure (non-slotted) Aloha as the medium access. In contrast the slotted model, the interference in pure Aloha may vary during the transmission of a tagged packet.

Two-step frequency conversion for connecting distant quantum memories by transmission through an optical fiber [PDF]
Japanese Journal of Applied Physics 57, 062801 (2018), 2018 Long-distance quantum communication requires entanglement between distant quantum memories. For this purpose, photon transmission is necessary to connect the distant memories. Here, for the first time, we develop a two-step frequency conversion process (from a visible wavelength to a telecommunication wavelength and back) involving the use of ...

Liquid-nitrogen cooled, free-running single-photon sensitive detector at telecommunication wavelengths [PDF]
Applied Physics B 118, 489-495 (2015), 2014 The measurement of light characteristics at the single- and few photon level plays a key role in many quantum optics applications. Often photodetection is preceded with the transmission of quantum light over long distances in optical fibers with their low loss window near 1550nm.

Adaptive Transmission Parameters Selection Algorithm for URLLC Traffic in Uplink [PDF]
, 2021 Ultra-Reliable Low-Latency Communications (URLLC) is a novel feature of 5G cellular systems. To satisfy strict URLLC requirements for uplink data transmission, the specifications of 5G systems introduce the grant-free channel access method. According to this method, a User Equipment (UE) performs packet transmission without requesting channel resources
