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 ...
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 ...
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 ...
