This paper investigates a channel estimator based on Gaussian mixture models (GMMs) in
the context of linear inverse problems with additive Gaussian noise. We fit a GMM to given …

We propose a versatile feedback scheme for both single-and multi-user multiple-input
multiple-output (MIMO) frequency division duplex (FDD) systems. Particularly, we propose …

Model-based method and data-based method are two basic approaches for the design of
wireless communication systems. Model-based methods suffer from inaccurate modeling …
