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 ... -
Channel Estimation and Hybrid Precoding for Frequency Selective Multiuser mmWave MIMO Systems
(IEEE, 2018-05)[Abstract]: Configuring the hybrid precoders and combiners in a millimeter wave multiuser multiple-input multiple-output system is challenging in frequency selective channels. In this paper, we develop a system that uses ... -
Hybrid Precoding With Time-Modulated Arrays for Mmwave MIMO Systems
(Institute of Electrical and Electronics Engineers, 2018)[Abstract]: We consider the utilization of time-modulated arrays (TMAs) as a simple and cost-effective approach to hybrid digital–analog precoding in millimeter wave (mmWave) multiple-input multiple-output (MIMO) systems. ...
