NOMA Versus Massive MIMO in Rayleigh Fading [PDF]
2019 IEEE 20th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2019 This paper compares the sum rates and rate regions achieved by power-domain NOMA (non-orthogonal multiple access) and standard massive MIMO (multiple-input multiple-output) techniques. We prove analytically that massive MIMO always outperforms NOMA in i.i.d.~Rayleigh fading channels, if a sufficient number of antennas are used at the base stations. The

Perspective: Hollow Core Optical Fibres for Ultraviolet and Visible Wavelengths
Advanced Science, EarlyView.Hollow core optical fibres bypass material constraints that limit optical fibres at ultraviolet and visible wavelengths. However, their challenging fabrication has limited their development, and significant gains in performance remain possible. In this perspective we outline approaches to enable the next generation of fibres for shorter wavelengths ...

Erasure Insertion in Reed-Solomon Coded SFH M-ary FSK with Partial-Band Interference and Rayleigh Fading for Non-Coherent Cooperative Communications [PDF]
, 2011 The rationale of our design is that although much of the literature of cooperative systems assumes perfect coherent detection, the assumption of having any channel estimates at the relays imposes an unreasonable burden on the relay station.

Bio‐Inspired Gradient Coatings Enhance the Leading Edge Erosion Resistance of Wind Blades
Advanced Science, EarlyView.Rain‐induced erosion of the wind turbine blade leading edge poses a critical challenge to maintenance and operation. Here, we propose a bio‐inspired approach for erosion protection utilising a platelet‐reinforced polyurethane coating with a graded through‐thickness architecture.

Fading Types in Wireless Communications Systems [PDF]
Journal of Electrical and Electronics Engineering, 2008 In this paper fading models areconsidered. In particular we divide the models intothree classes by separating the received signal in threescale of spatial variation such as fast fading, slow fading(shadowing) and path loss.
