Sparsity and Resolvability: Re-evaluating Channel Representations For Next Generation Networks
Hamza Haif, Abdelali Arous, Huseyin Arslan
As wireless networks transition toward 6G, high mobility, clustered scattering, and hardware impairments increasingly challenge classical assumptions on channel sparsity, resolvabi…
Channel-Aware Waveform Selection Criteria Across Different Waveform Domains
Hamza Haif, Abdelali Arous, Huseyin Arslan
Waveform evaluation for sixth generation (6G) networks has largely relied on sparse and quasi-stationary channel models that enabled mathematical tractability, diversity gains, and…
Waveform-domain NOMA: An Enabler for ISAC in Uplink Transmission
Jialiang Zhu, Hamza Haif, Abdelali Arous +2
According to the recent 3GPP decisions on 6G air interface, orthogonal frequency-division multiplexing (OFDM)-based waveforms are the primary candidates for future integrated sensi…
Enabling Full Duplex ISAC Leveraging Waveform Domain Separability
Abdelali Arous, Hamza Haif, Huseyin Arslan
Integrated sensing and communication (ISAC) in monostatic in-band full-duplex (IBFD) systems encounters significant challenges due to self-interference (SI) at the radar receiver d…
A Unified Framework for Adaptive Waveform Processing in Next Generation Wireless Networks
Abdelali Arous, Hamza Haif, Arman Farhang +1
The emergence of alternative multiplexing domains to the time-frequency domains, e.g., the delay-Doppler and chirp domains, offers a promising approach for addressing the challenge…
