Device Activity Detection and Non-Coherent Information Transmission for Massive Machine-Type Communications [PDF]

open access: yesIEEE Access, 2020
In the grant-free massive machine-type communication (mMTC) scenario, a key challenge is the joint device activity detection and data decoding. The sporadic nature of mMTC makes compressed sensing a promising solution to the activity detection problem ...

Emulation of coherent absorption of Fock-state quantum light in a programmable linear photonic circuit [PDF]

open access: yesNature Communications
Non-Hermitian quantum systems, governed by nonunitary evolution, offer powerful tools for manipulating quantum states through engineered loss. A prime example is coherent absorption, where quantum states undergo phase-dependent partial or complete ...

Back to sources – the role of losses and coherence in super-resolution imaging revisited [PDF]

open access: yesQuantum, 2022
Photon losses are intrinsic for any translationally invariant optical imaging system with a non-trivial Point Spread Function, and the relation between the transmission factor and the coherence properties of an imaged object is universal – we demonstrate

Centralized and Distributed Schedulers for Non-Coherent Joint Transmission [PDF]

open access: yes2018 IEEE Globecom Workshops (GC Wkshps), 2018
This paper studies the performance of three typical network coordination schemes, i.e., dynamic point selection, fully overlapped non-coherent joint transmission (F-NCJT), and nonfully overlapped NCJT (NF-NCJT), in 3GPP new radio (NR) in indoor scenarios via system level simulation.

Frequency allocation in non-coherent joint transmission CoMP networks [PDF]

open access: yes2014 IEEE International Conference on Communications Workshops (ICC), 2014
In this paper, we study the problem of joint transmission (JT) in coordinated multipoint (CoMP) networks from a new point of view where the system performance is optimized via frequency allocation for 5G small cells. Moreover, we investigate the implementation of hybrid automatic repeat request (HARQ), as an efficient scheme facing the feedback load ...
