SVD-Based Technique for Interference Cancellation and Noise Reduction in NMR Measurement of Time-Dependent Magnetic Fields

Sensors, 2016
A nuclear magnetic resonance (NMR) experiment for measurement of time-dependent magnetic fields was introduced. To improve the signal-to-interference-plus-noise ratio (SINR) of NMR data, a new method for interference cancellation and noise reduction ...

Robust Spectral and Energy Efficiency Tradeoff for RIS‐Aided Multi‐User Communication

IET Communications, Volume 20, Issue 1, January/December 2026.
In this work, an RIS‐aided multi‐user network with imperfect CSI is investigated. Correspondingly, we focus on balancing SE and EE through the collaborative design of the base station (BS)'s precoding matrix and the RIS's phase shifts, which consider the transmit power budget and the channel uncertainties constraints.

Random Matrix Theory Predictions of Dominant Mode Rejection SINR Loss due to Signal in the Training Data

IEEE Open Journal of Signal Processing
Detection and estimation performance depends on signal-to-interference-plus-noise ratio (SINR) at the output of an array. The Capon beamformer (BF) designed with ensemble statistics achieves the optimum SINR in stationary environments.

Exploring Missed Spectrum Access Opportunities in Wi‐Fi 6 and 5G NR‐U Coexistence for Enhancing 6 GHz Spectrum Utilization

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper investigates new radio spectrum coexistence mechanisms, leveraging the currently uninhabited 6 GHz bands and aiming for fair coexistence of Wi‐Fi 6 and 5G new radio unlicensed (NR‐U). A novel two‐stage channel contention mechanism is proposed to explore additional spectrum access opportunities which remain unrealized in the existing channel ...

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.

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

Signal design based on post‐detection SINR for MIMO radar in the presence of signal‐dependent interference

IET Radar, Sonar & Navigation, 2022
In this study, the target detection and signal design problems in the presence of signal‐dependent interference for a colocated multiple‐input multiple‐output (MIMO) radar employing a space‐(slow) time transmit signal are addressed.

Artificial Noise Aided Directional Modulation with Multilog Frequency Diverse Array

IET Communications, Volume 20, Issue 1, January/December 2026.
The basic principle of the proposed AN‐DM‐MFDA system is to allocate AN to leakage sidelobes instead of uniformly transmitting on the two‐dimensional plane. Moreover, we theoretically derive the average bit error rates as well as the secrecy capacity between the legitimate receiver and eavesdropper in the developed system.
