Design of Linear Precoders for Correlated Sources in MIMO Multiple Access Channels
(Institute of Electrical and Electronics Engineers, 2018-12)
[Abstract]: This paper focuses on distributed linear precoding when users transmit correlated information over a fading multiple-input and multiple-output multiple access channel. The precoders are optimized in order to ...
Channel Covariance Identification in FDD Massive MIMO Systems
(IEEE, 2018-11)
[Abstract]: Many channel estimation methods in Massive MIMO FDD systems usually rely on the knowledge of the channel covariance matrix to operate. However, in real scenarios, this covariance is not known beforehand, and ...
Analog Transmission of Spatio-Temporal Correlated Sources Over MAC With Modulo Mappings
(Institute of Electrical and Electronics Engineers, 2018-05)
[Abstract]: Modulo mappings is an appealing scheme for the analog transmission of spatially correlated discrete-time analog source symbols over multiple access channels. In this letter, we show that the modulo mappings are ...
