FDD Channel Estimation Via Covariance Estimation in Wideband Massive MIMO Systems
(M D P I AG, 2020-02-10)
[Abstract] A method for channel estimation in wideband massive Multiple-Input Multiple-Output systems using hybrid digital analog architectures is developed. The proposed method is useful for Frequency-Division Duplex at ...
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 ...
User Grouping for the Uplink of Multiuser Hybrid mmWave MIMO
(Institute of Electrical and Electronics Engineers, 2020-03-16)
[Abstract] Hybrid analog/digital schemes for precoding/combining have proved to be a low-complexity and/or low-power strategy to obtain reasonable beamforming gains in multiuser millimeter-wave (mmWave) multiple-input ...
