A Unified Framework for Pulse-Shaping on Delay-Doppler Plane
Mohsen Bayat, Arman Farhang
Delay-Doppler multiplexing has recently stirred a great deal of attention in research community. While multiple studies have investigated pulse-shaping aspects of this technology,…
Downlink Transmission in FBMC-based Massive MIMO with Co-located and Distributed Antennas
Hamed Hosseiny, Arman Farhang, Behrouz Farhang-Boroujeny
This paper introduces a practical precoding method for the downlink of Filter Bank Multicarrier-based (FBMC-based) massive multiple-input multiple-output (MIMO) systems. The propos…
A Generalized Framework for Pulse-Shaping on Delay-Doppler Plane
Mohsen Bayat, Arman Farhang
The primary objective of this paper is to establish a generalized framework for pulse-shaping on the delay-Doppler plane. To this end, we classify delay-Doppler pulse-shaping techn…
Truncated Turbo Equalizer with SIC for OTFS
Sanoopkumar P. S., Stephen McWade, Arman Farhang
Orthogonal time frequency space (OTFS) is a promising candidate waveform for the next generation wireless communication systems. OTFS places data in the delay-Doppler (DD) domain,…
Low-Complexity Reliability-Based Equalization and Detection for OTFS-NOMA
Stephen McWade, Arman Farhang, Mark F. Flanagan
Orthogonal time frequency space (OTFS) modulation has recently emerged as a potential 6G candidate waveform which provides improved performance in high-mobility scenarios. In this…
Practical Synchronization for OTFS
Mohsen Bayat, Sanoopkumar P. S., Arman Farhang
In the existing literature on joint timing and frequency synchronization of orthogonal time frequency space modulation (OTFS), practically infeasible impulse pilot with large peak-…
RIS Meets Aerodynamic HAPS: A Multi-objective Optimization Approach
Arman Azizi, Arman Farhang
In this paper, we propose a novel network architecture for integrating terrestrial and non-terrestrial networks (NTNs) to establish connection between terrestrial ground stations w…
