Distributed Information Bottleneck for a Primitive Gaussian Diamond MIMO Channel

Yi Song, Hao Xu, Kai-Kit Wong +2

This paper considers the distributed information bottleneck (D-IB) problem for a primitive Gaussian diamond channel with two relays and MIMO Rayleigh fading. The channel state is a…

Deep-Learning Aided Channel Training and Precoding in FDD Massive MIMO with Channel Statistics Knowledge

Yi Song, Tianyu Yang, Mahdi Barzegar Khalilsarai +1

We propose a method for channel training and precoding in FDD massive MIMO based on deep neural networks (DNNs), exploiting Downlink (DL) channel covariance knowledge. The DNN is o…

FDD Massive MIMO Channel Training Optimal Rate Distortion Bounds and the Efficiency of one-shot Schemes

Mahdi Barzegar Khalilsarai, Yi Song, Tianyu Yang +1

We study the problem of providing channel state information (CSI) at the transmitter in multi-user massive MIMO systems operating in frequency division duplexing (FDD). The wideban…

Channel State Acquisition in FDD Massive MIMO: Rate-Distortion Bound and Effectiveness of "Analog" Feedback

Mahdi Barzegar Khalilsarai, Yi Song, Tianyu Yang +1

We consider the problem of estimating channel fading coefficients (modeled as a correlated Gaussian vector) via Downlink (DL) training and Uplink (UL) feedback in wideband FDD mass…

Uplink-Downlink Channel Covariance Transformations and Precoding Design for FDD Massive MIMO

Mahdi Barzegar Khalilsarai, Yi Song, Tianyu Yang +2

A large majority of cellular networks deployed today make use of Frequency Division Duplexing (FDD) where, in contrast with Time Division Duplexing (TDD), the channel reciprocity d…

Machine Learning for Geometrically-Consistent Angular Spread Function Estimation in Massive MIMO

Yi Song, Mahdi Barzegar Khalilsarai, Saeid Haghighatshoar +1

In the spatial channel models used in multi-antenna wireless communications, the propagation from a single-antenna transmitter (e.g., a user) to an M-antenna receiver (e.g., a Base…
