    • Downlink Transmission in FBMC-based Massive MIMO with Co-located and Distributed Antennas 

      Farhang, Arman (2024)
      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 proposed method comprises a two-stage precoder, ...

    • Joint Channel Estimation and Equalization in Massive MIMO Using a Single Pilot Subcarrier 

      Lelin Li, Danilo; Farhang, Arman (2023)
      The focus of this letter is on the reduction of the large pilot overhead in orthogonal frequency division multi-plexing (OFDM) based massive multiple-input multiple-output (MIMO) systems. We propose a novel joint channel ...

    • Low-Complexity Equalization and Detection for OTFS-NOMA 

      McWade, Stephen; Flanagan, Mark; Farhang, Arman (2023)
      Orthogonal time frequency space (OTFS) modula- tion has recently emerged as a potential 6G candidate waveform which provides improved performance in high-mobility scenarios. In this paper we investigate the combination ...

    • Low-Complexity Reliability-Based Equalization and Detection for OTFS-NOMA 

      McWade, Stephen; Farhang, Arman; Flanagan, Mark (2023)
      Orthogonal time frequency space (OTFS) modula- tion has recently emerged as a potential 6G candidate waveform which provides improved performance in high-mobility scenarios. In this paper we investigate the combination ...

    • A Practical Pilot for Channel Estimation of OTFS 

      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. ...

    • Time and Frequency Synchronization for OTFS 

      Bayat, Mohsen; Farhang, Arman (2022)
      In this letter, we propose timing offset (TO) and carrier frequency offset (CFO) estimators for orthogonal time frequency space modulation (OTFS). The proposed estimators do not require any additional training overheads ...

    • Truncated Turbo Equalizer with SIC for OTFS 

      Farhang, Arman (2023)
      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, which simplifies channel estimation in ...
