ADAPTIVE ARRAY SYSTEM FOR JAMMING SOURCES CANCELLATION IN TWO DIMENSIONAL PLANES

Journal of Engineering and Sustainable Development, 2016
The aim of this paper is to enhance the desired signal reception while suppressing the reception of inference signals to get maximum signal to interference plus noise ratio (SINR) at the output.

A Probability‐Aware AI Framework for Reliable Anti‐Jamming Communication

CAAI Transactions on Intelligence Technology, Volume 11, Issue 2, Page 349-366, April 2026.
ABSTRACT Adversarial jamming attacks have increased on communication systems, causing distortion and threatening transmissions. Typical attacks rely on traditional, well‐defined cryptographic protocols and frequency‐hopping techniques. Nevertheless, these techniques become vulnerable when facing intelligent jammers.

Dynamic Resource Allocation for LEO Satellite Systems Under Heterogeneous Traffic Distributions

International Journal of Satellite Communications and Networking, Volume 44, Issue 2, Page 199-209, March/April 2026.
ABSTRACT This paper proposes an efficient resource allocation scheme for low Earth orbit (LEO) satellite systems. Taking into account the unique characteristics of LEO systems for 6G communication services, we introduce a dynamic bandwidth and power allocation scheme specifically designed to accommodate highly heterogeneous traffic distributions.

Interference Mitigation Method for Millimeter-Wave Frequency-Modulation Continuous-Wave Radar Based on Outlier Detection and Variational Modal Decomposition

Remote Sensing, 2023
Aiming at the problem of mutual interference between millimeter-wave frequency-modulation continuous-wave (FMCW) radars, an interference mitigation method based on outlier detection and variational mode decomposition (VMD) is proposed in this paper ...

Evaluation of multi‐user multiple‐input multiple‐output digital beamforming algorithms in B5G/6G low Earth orbit satellite systems

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 17-33, January/February 2026.
In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such
