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) ... -
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 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 ...
