Enabling Asynchronous Machine-Type D2D Communication Using Multiple Waveforms in 5G
Marchetti, Nicola; Farhang, Arman (2018) -
FBMC Receiver Design and Analysis for Medium and Large Scale Antenna Systems
Farhang, Arman (2022)In this paper, we design receivers for filter bank multicarrier-based (FBMC-based) massive MIMO considering practical aspects such as channel estimation and equalization. In particular, we propose a spectrally efficient ... -
Low-Complexity Joint CFO and Channel Estimation for RIS-aided OFDM Systems
Farhang, Arman (2021)Accurate channel estimation is essential for achieving the performance gains offered by reconfigurable intelligent surface (RIS)-aided wireless communications. A variety of channel estimation methods have been proposed ... -
Multi-operator connectivity sharing for reliable networks: a data-driven risk analysis
Gomes Santos Gonçalves, André Vinícius; Farhang, Arman (2021)A key distinction between today’s and future networks is the appetite for reliable communication to support emerging critical-communication services. In this paper, we study multi-operator connectivity as a form of redundancy ... -
Multiuser communications for next generation wireless networks
Farhang, Arman (Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2015)Orthogonal frequency division multiplexing (OFDM) has been the technology of choice for years in wired and wireless systems. However, it has some drawbacks that limit its use in the fifth generation of wireless communication ... -
Network Sharing for Reliable Networks: A Data-Driven Study
Gomes Santos Gonçalves, André Vinícius; Farhang, Arman (2020)The next generation of mobile networks will bring an appetite for reliable communication, which enables emerging critical-communication services. In this paper, we present network sharing between operators as a way to ... -
A Practical Pilot for Channel Estimation of OTFS
P. S., Sanoopkumar; Farhang, Arman (2023)The widely used embedded impulse pilot for channel estimation of orthogonal time frequency space modulation (OTFS) has a prohibitively large peak to average power ratio (PAPR). Hence, in this paper, we propose a novel ... -
Practical Synchronization for OTFS
Farhang, Arman (2023)In the existing literature on joint timing and frequency synchronization of orthogonal time frequency space modulation (OTFS), practically infeasible impulse pilot with large peak-to-average power ratio (PAPR) is deployed. ... -
Resource Allocation for Mixed Numerology NOMA
Farhang, Arman (2021)6G wireless networks will require the flexibility to accommodate an extremely diverse set of service types. Accommodating different quality of service (QoS) requirements for these service types necessitates the use of mixed ...
