Abstract: This paper considers the contaminated channel estimation in multicell very large multiuser multiple-input multiple-output networks. To provide desirable spectral efficiency of these systems, we propose two adaptive algorithms which their implementations do not require orthogonal… read more here.

DOI: 10.1109/lcomm.2022.3181699
Abstract: This letter proposes a structured CANDECOMP/PARAFAC (CP) decomposition-aided (SCPD) pilot decontamination (PDC) scheme for UAV communication in cell-free massive MIMO systems. We design a two-stage pilot transmission scheme and intentionally generate pilot contamination for pilot… read more here.

DOI: 10.1109/tvt.2019.2949605
Abstract: Pilot contamination has been recognized as one of the main limiting factors in massive multiple-input multiple-output (MIMO) since it damages the acquisition of accurate channel state information (CSI) at base stations. In this work, we… read more here.
