FDD Massive MIMO: Efficient Downlink Probing and Uplink Feedback via Active Channel Sparsification
Mahdi Barzegar Khalilsarai, Saeid Haghighatshoar, Xinping Yi +1
In this paper, we propose a novel method for efficient implementation of a massive Multiple-Input Multiple-Output (massive MIMO) system with Frequency Division Duplexing (FDD) oper…
Efficient Downlink Channel Probing and Uplink Feedback in FDD Massive MIMO Systems
Mahdi Barzegar Khalilsarai, Saeid Haghighatshoar, Giuseppe Caire
Massive Multiple-Input Multiple-Output (massive MIMO) is a variant of multi-user MIMO in which the number of antennas at each Base Station (BS) is very large and typically much lar…
Compressive Estimation of a Stochastic Process with Unknown Autocorrelation Function
Mahdi Barzegar Khalilsarai, Saeid Haghighatshoar, Giuseppe Caire +1
In this paper, we study the prediction of a circularly symmetric zero-mean stationary Gaussian process from a window of observations consisting of finitely many samples. This is a…
