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.

Multiple-Symbol Detection Aided Differential Spatial Division Multiple Access [PDF]
, 2011 This paper presents a multiple-symbol differential spatial division multiple access (MS-DSDMA) system conceived for low-complexity and high-bandwidth-efficiency applications operating in time-varying fading channels, where no channel estimation is ...

IET Communications, 2014 Jamming in defence applications is increasingly difficult because of advanced signal processing countermeasures. In this study, task‐dependent power‐constraint optimal jamming techniques are investigated. To prevent the target from being detected, a novel jamming technique is proposed to minimise the signal‐to‐interference‐plus‐noise ratio (SINR) of ...

International Journal of Distributed Sensor Networks, 2017 As we know, the degree of freedom approximates the capacity of a network. To improve the achievable degree of freedom in the K -user interference network, we propose a rank minimization interference minimization algorithm.

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.

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.

Molecular Oncology, EarlyView.A urine‐based digital PCR assay targeting two hotspot TERT promoter variants detected bladder cancer with high sensitivity and no false positives in this case–control cohort. The streamlined AbsoluteQ workflow outperformed Sanger sequencing and supports non‐invasive molecular testing for bladder cancer detection.
