Beam Squinting Effects in Super Wideband Communication Systems
Sachitha C. Bandara, Peter J. Smith, Erfan Khordad +3
Beam squint, the frequency-dependent shift of the main beam, poses a major challenge for wideband antenna arrays. This paper focuses on the beam squint effects in super wideband (S…
Constant Modulus Waveforms for IoT-Centric Integrated Sensing and Communications
Tian Han, Shalanika Dayarathna, Rajitha Senanayake +5
Integrated sensing and communications (ISAC) is considered a key enabler to support application scenarios such as the Internet-of-Things (IoT) in which both communications and sens…
Target Detection with Tightly-coupled Antennas: Analysis for Unknown Wideband Signals
Erfan Khordad, Peter J. Smith, Sachitha C. Bandara +2
This paper presents analysis for target detection using tightly-coupled antenna (TCA) arrays with high mutual coupling (MC). We show that the wide operational bandwidth of TCAs is…
Dynamic Length FSK Waveforms for Joint Communications and Radar
Tian Han, Peter J Smith, Urbashi Mitra +3
Motivated by the constant modulus property of frequency shift keying (FSK) based waveforms and the stabilisation of its radar performance with an increase in the number of subpulse…
Rician Channel Modelling for Super Wideband MIMO Communications
Sachitha C. Bandara, Peter J. Smith, Erfan Khordad +2
Recent developments in Multiple-Input-Multiple-Output (MIMO) technology include packing a large number of antenna elements in a compact array to access the bandwidth benefits provi…
