Cognitive GFDM Full-Duplex Radios With RF Impairments and ACI Constraints
IEEE Open Journal of the Communications Society, 2020 We investigate the problem of sum-rate maximization of a secondary link of full-duplex generalized frequency division multiplexing (GFDM) radios operating over a spectrum hole, which is surrounded by two active primary adjacent channels.

IET Communications, 2019 In mobile communication networks, the handover procedure enables a continuous communication service for users on the move. However, handovers, handover failures, and ping‐pong handovers increase the signalling load in the network, resulting in the use of network resources and a reduction of the system throughput.

An efficient method to measure reliability of underwater acoustic communication links
Journal of Ocean Engineering and Science, 2016 We consider the problem of evaluating the reliability of underwater acoustic communication (UWAC) systems. Reliability is a requirement for any communication system and is often defined as the probability to achieve a target bit error rate. Evaluation of

High Performance Robust Adaptive Beamforming in the Presence of Array Imperfections
International Journal of Antennas and Propagation, 2016 A high performance robust beamforming scheme is proposed to combat model mismatch. Our method lies in the novel construction of interference-plus-noise (IPN) covariance matrix. The IPN covariance matrix consists of two parts.

A novel adaptive beamforming scheme for array signal data processing
EURASIP Journal on Wireless Communications and Networking, 2023 When the desired signal data exists in the array received data or the steering vector has a mismatch problem, the current traditional adaptive beamformers will suffer from the effect of the desired signal cancelation phenomenon, resulting in a sharp ...

Molecular Oncology, EarlyView.This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Efficient joint power allocation for mitigating intracluster interference in clustered NOMA system
ETRI JournalIn recent years, the growing demand for massive connectivity has focused researchers’ attention on next-generation radio access techniques. Nonortho-gonal multiple access (NOMA) is a candidate for supporting massive connec-tivity.

Joint Design of Intelligent Reflecting Surface Configuration and Precoding in MISO-VLC Systems
PhotonicsTo address the problem of insufficient user fairness in multi-user multiple-input single-output visible light communication systems, this paper proposes a joint design scheme of intelligent reflecting surface configuration and precoding to maximize the ...

Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.
