A Rank-Constrained Coordinate Ascent Approach to Hybrid Precoding for the Downlink of Wideband Massive (MIMO) Systems
(Institute of Electrical and Electronics Engineers, 2023-12)[Abstract]: An innovative approach to hybrid analog-digital precoding for the downlink of wideband massive MIMO systems is developed. The proposed solution, termed Rank-Constrained Coordinate Ascent (RCCA), starts seeking ... -
Alternating Minimization for Wideband Multiuser IRS-Aided MIMO Systems Under Imperfect CSI
(Institute of Electrical and Electronics Engineers, 2023-11-28)[Abstract]: This work focuses on wideband intelligent reflecting surface (IRS)-aided multiuser MIMO systems. One of the major challenges of this scenario is the joint design of the frequency-dependent base station (BS) ... -
Hybrid LISA for Wideband Multiuser Millimeter-Wave Communication Systems Under Beam Squint
(IEEE, 2019-02)[Abstract]: This paper jointly addresses user scheduling and precoder/combiner design in the downlink of a wideband millimeter-wave communications system. We consider the orthogonal frequency-division multiplexing modulation ...
