  • Linear interference cancellation for the cell-free C-RAN uplink
    Mosayebi, Reza; Mojahedian, Mohammad Mahdi; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Drawing on the notion of parallel interference cancellation, this paper formulates a one-shot linear receiver for the uplink of centralized, possibly cloud-based, radio access networks (C-RANs) operating in a cell-free ...
  • Parallel interference cancellation for Cell-Free C-RANs
    Mosayebi, Reza; Mojahedian, Mohammad Mahdi; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    This paper formulates a linear receiver for the uplink of centralized, possibly cloud-based, radio access networks operating in a cell-free fashion. This receiver, which draws on the notion of soft parallel interference ...
  • Pseudo-Inverse vs generalized inverse for C-RAN downlink precoding
    Mojahedian, Mohammad Mahdi; Mosayebi, Reza; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    This paper tackles the problem of zero-forcing (ZF) precoding for the downlink of centralized radio-access networks operating in a cell-free fashion. While the customary workhorse of ZF precoding is the channel pseudo-inverse, ...
  • Spatial-wideband effect in line-of-sight MIMO communication
    Mojahedian, Mohammad Mahdi; Attarifar, Masoud; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2022)
    This paper addresses the spatial-wideband effect in line-of-sight multiple-input multiple-output channels. This effect arises once the bandwidth is large enough that the differences in propagation delays for distinct ...
  • Subset regularized zero-forcing precoders for cell-free C-RANs
    Mojahedian, Mohammad Mahdi; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    This paper formulates regularized zero-forcing (RZF) precoders that are both network- and user-centric for the downlink of centralized radio-access networks operating in a cell-free fashion. The transmission to every user ...
