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 ...
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 ...
