Range–Doppler Estimation With an EM‐Learned Prior for Pulse‐Agile Waveforms
Electronics Letters, Volume 62, Issue 1, January/December 2026.This letter proposes an expectation–maximisation (EM)‐based range–Doppler (RD) estimator that adaptively learns the clutter and target distributions and adjusts an RD prior map. By optimising the shrinkage strength via prior weighting, the proposed method improves RSM suppression in the region of interest.

Correlation-based blind SINR estimation with statistical theoretic analysis for OFDM systems
EURASIP Journal on Advances in Signal ProcessingA blind signal-to-interference-plus-noise ratio (SINR) estimation method is proposed for orthogonal frequency division multiplex (OFDM) systems in the presence of impulse noise over multipath fading channels.

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.

Electronics Letters, Volume 62, Issue 1, January/December 2026.We propose a Doppler‐tolerant DFT‐spread orthogonal time‐coded OFDM (DSS‐OTC‐OFDM) waveform for MIMO radar that maintains orthogonality under Doppler shifts while enabling flexible code design. An optimisation framework is developed to minimise peak sidelobe level (PSL) and suppress cross‐correlation after matched filtering across a range of Doppler ...

Approximation Algorithms for Maximum Link Scheduling under SINR-Based Interference Model
International Journal of Distributed Sensor Networks, 2015 A fundamental problem in wireless networks is the maximum link scheduling (MLS) problem. In this problem, interference is a key issue and past researchers have shown that determining reception using Signal-to-Interference plus Noise Ratio (SINR) is more ...
