Impact of Residual Hardware Impairments on Joint Transmission-CoMP-Cooperative NOMA Networks

IEEE Access
This paper considers the interference of imperfect successive interference cancellation operation and hardware noise in the joint transmission of coordinated multipoint cooperative non-orthogonal multiple access (NOMA) networks. Presumably, the statement

MCRB-based Performance Analysis of 6G Localization under Hardware Impairments

, 2022
Location information is expected to be the key to meeting the needs of communication and context-aware services in 6G systems. User localization is achieved based on delay and/or angle estimation using uplink or downlink pilot signals.

Multiscale Microscopy via Automation: Dual Magnification Environmental Scanning Electron Microscopy Imaging by Frame Alternation

Advanced Materials Technologies, EarlyView.
An automation interface for environmental scanning electron microscopy (ESEM) enables simultaneous, interlaced data sets via frame‐by‐frame parameter changes. Demonstrated on oscillatory hydrogen oxidation over cobalt (Co) foil, dual‐magnification imaging bridges mesoscopic to microscopic length scales, capturing alternating views of surface dynamics ...

Near-field Target Localization: Effect of Hardware Impairments

CoRR
The prior works on near-field target localization have mostly assumed ideal hardware models and thus suffer from two limitations in practice. First, extremely large-scale arrays (XL-arrays) usually face a variety of hardware impairments (HIs) that may introduce unknown phase and/or amplitude errors.

Power Switching Protocol for Two-way Relaying Network under Hardware Impairments [PDF]

Radioengineering, 2015
In this paper, we analyze the impact of hardware impairments at relay node and source node (i.e. imperfect nodes) on network performance by evaluating outage probability based on the effective signal to noise and distortion ratio (SNDR).
