Low-Complexity Distance-Based Scheduling for Multi-User XL-MIMO Systems
(IEEE, 2021-11)[Abstract]: We introduce Distance-Based Scheduling (DBS), a new technique for user selection in downlink multi-user communications with extra-large (XL) antenna arrays. DBS categorizes users according to their equivalent ... -
Power Efficient Scheduling and Hybrid Precoding for Time Modulated Arrays
(Institute of Electrical and Electronics Engineers, 2020-01-22)[Abstract] We consider power efficient scheduling and precoding solutions for multiantenna hybrid digital-analog transmission systems that use Time-Modulated Arrays (TMAs) in the analog domain. TMAs perform beamforming ... -
Rank Constrained Precoding for the Downlink of mmWave Massive MIMO Hybrid Systems
(Institute of Electrical and Electronics Engineers, 2021-02-11)[Abstract] The hybrid design of precoding schemes for millimeter-wave communications allows exploiting the gains by using large antenna array with an affordable hardware cost and power consumption. In this work, we present ... -
Robust Precoding with Bayesian Error Modeling for Limited Feedback MU-MISO Systems
(IEEE, 2010)[Abstract] We consider the robust precoder design for multiuser multiple-input single-output (MU-MISO) systems where the channel state information (CSI) is fed back from the single antenna receivers to the centralized ... -
Wideband Hybrid Precoding Using Time Modulated Arrays
(Institute of Electrical and Electronics Engineers, 2020-08-05)[Abstract] Hybrid digital-analog precoding is a cost effective solution for transmitting over the large bandwidths and huge antenna arrays available in the millimeter wave frequency bands. In this work we focus on the ...
