DOI: 10.1007/s11276-019-02030-6
Abstract: In this paper we consider a single-cell massive multiple-input-multiple-output scenario, where the number of base station (BS) antennas is larger than the number of single antenna user terminals (UTs). We study and investigate common impairment… read more here.

DOI: 10.1109/lcomm.2018.2812891
Abstract: In this letter, we introduce a novel pilot design approach that minimizes the total mean square errors of the minimum mean square error estimators of all base stations (BSs) subject to the transmit power constraints… read more here.

DOI: 10.1109/tcomm.2022.3194144
Abstract: We consider the downlink of a multi-cell massive MIMO system suffering from asymptotic rate saturation due to pilot contamination. As opposed to treating pilot contamination interference as noise (TIN), we study the performance of decoding… read more here.

DOI: 10.1109/twc.2017.2787702
Abstract: This paper considers pilot design to mitigate pilot contamination and provide good service for everyone in multi-cell massive multiple-input-multiple-output systems. Instead of modeling the pilot design as a combinatorial assignment problem, as in prior works,… read more here.
