Channel covariance estimation in multiuser massive MIMO systems with an approach based on infinite dimensional Hilbert spaces [article]

Renato Luis Garrido Cavalcante, Slawomir Stanczak
2020 arXiv   pre-print
We propose a novel algorithm to estimate the channel covariance matrix of a desired user in multiuser massive MIMO systems.  ...  To derive the algorithm, we study interference patterns with realistic models that treat signals as continuous functions in infinite dimensional Hilbert spaces.  ...  All these results require connections between the angular power spectra, the channel covariance matrices, and the antenna array response in an infinite dimensional Hilbert space.  ...

Structured Channel Covariance Estimation from Limited Samples for Large Antenna Arrays [article]

Tianyu Yang, Mahdi Barzegar Khalilsarai, Saeid Haghighatshoar, Giuseppe Caire
2022 arXiv   pre-print
In massive multiple-input multiple-output (MIMO) systems, the knowledge of the users' channel covariance matrix is crucial for minimum mean square error (MMSE) channel estimation in the uplink as well  ...  As a result, the standard sample covariance estimator may yield a too large estimation error which in turn may yield significant system performance degradation with respect to the ideal channel covariance  ...  CONCLUSION In this work, we addressed the problem of estimating the covariance matrix of the channel vector from a set of noisy UL pilot observations in massive MIMO systems.  ...
