Beyond the Use-and-then-Forget (UatF) Bound: Fixed Point Algorithms for Statistical Max-Min Power Control
Renato Luis Garrido Cavalcante, Noor Ul Ain, Lorenzo Miretti +1
We introduce mathematical tools and fixed point algorithms for optimal statistical max-min power control in cellular and cell-less massive MIMO systems. Unlike previous studies tha…
FDD massive MIMO channel spatial covariance conversion using projection methods
Lorenzo Miretti, Renato L. G. Cavalcante, Slawomir Stanczak
Knowledge of second-order statistics of channels (e.g. in the form of covariance matrices) is crucial for the acquisition of downlink channel state information (CSI) in massive MIM…
Error Bounds for FDD Massive MIMO Channel Covariance Conversion with Set-Theoretic Methods
Renato Luis Garrido Cavalcante, Lorenzo Miretti, Slawomir Stanczak
We derive novel bounds for the performance of algorithms that estimate the downlink covariance matrix from the uplink covariance matrix in frequency division duplex (FDD) massive m…
Downlink channel spatial covariance estimation in realistic FDD massive MIMO systems
Lorenzo Miretti, Renato L. G. Cavalcante, Slawomir Stanczak
The knowledge of the downlink (DL) channel spatial covariance matrix at the BS is of fundamental importance for large-scale array systems operating in frequency division duplexing…
