Optimal and efficient power allocation for OFDM non-coherent cooperative transmission [PDF]
In this paper, we study the subchannel (SC) power allocation for orthogonal frequency division multiplexing (OFDM) multiple access points (APs) systems with non-coherent cooperative transmission. The objective is to maximize the total capacity under per-AP power constraints.

DLI-Based DP-QPSK Reception Scheme for Short-Range Optical Communication
The unacceptably high cost of digital coherent receivers for short-range optical communication has in recent years fueled the study of alternative transmission schemes that are simultaneously highly performing and cost-effective.

Squeezing-enhanced communication without a phase reference [PDF]
We study the problem of transmitting classical information using quantum Gaussian states on a family of phase-noise channels with a finite decoherence time, such that the phase-reference is lost after $m$ consecutive uses of the transmission line.

Sixty Years of Coherent Versus Non-Coherent Tradeoffs and the Road From 5G to Wireless Futures
Sixty years of coherent versus non-coherent tradeoff as well as the twenty years of coherent versus non-coherent tradeoff in Multiple-Input Multiple-Output (MIMO) systems are surveyed. Furthermore, the advantages of adaptivity are discussed.

Average SER analysis of two‐hop WP DF relay system under κ−μ shadowed fading
This paper investigates the performance of a two‐hop decode‐and‐forward relaying system when the source node is energy‐constrained and it harnesses energy using the radio frequency signal radiated by the relay node.

Non-Orthogonality Measure for a Collection of Pure Quantum States
Modern optical communication technology can realize a large-scale multilevel (or M-ary) optical signal. Investigating the quantum mechanical nature of such a large-scale M-ary optical signal is essential for a unified understanding of quantum information

Characterizing decoherence rates of a superconducting qubit by direct microwave scattering
We experimentally investigate a superconducting qubit coupled to the end of an open transmission line, in a regime where the qubit decay rates to the transmission line and to its own environment are comparable.
