Semi-Blind Channel Estimation in Massive Mimo Systems with Different Priors on Data Symbols
ICASSP 2018accepted
This paper investigates semi-blind channel estimation in massive multiple-input multiple-output (MIMO) systems using different priors on data symbols. We derive two tractable expectation-maximization (EM) based channel estimation algorithms; one based on a Gaussian prior and the other one based on a…
