Modified conjugate beamforming for cell-free massive MIMO

Attarifar, Masoud; Abbasfar, Aliazam; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2019)

We present a modification of conjugate beamforming for the forward link of cell-free massive MIMO networks. This modification eliminates the self-interference and yields a performance that, without forward pilots, closely ...
Random vs structured pilot assignment in cell-free massive MIMO wireless networks

Attarifar, Masoud; Abbasfar, Aliazam; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2018)

This paper addresses the performance improvement that structured pilot assignment policies can bring about, relative to a random pilot assignment, in cell-free massive MIMO wireless networks. It is shown that structured ...
Subset MMSE receivers for cell-free networks

Attarifar, Masoud; Abbasfar, Aliazam; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2020)

This paper formulates linear MMSE receivers that are both network- and user-centric for the uplink of cell-free wireless networks with centralized processing. Precisely, every user’s reception involves a distinct subset ...
