Design of an Efficient CSI Feedback Mechanism in Massive MIMO Systems: A Machine Learning Approach using Empirical Data
Muhammad Karam Shehzad, Luca Rose, Stefan Wesemann +2
Massive multiple-input multiple-output (mMIMO) regime reaps the benefits of spatial diversity and multiplexing gains, subject to precise channel state information (CSI) acquisition…
Quantized Precoding for Multi-Antenna Downlink Channels with MAGIQ
Andrei Nedelcu, Fabian Steiner, Markus Staudacher +5
A multi-antenna, greedy, iterative, and quantized (MAGIQ) precoding algorithm is proposed for downlink channels. MAGIQ allows a straightforward integration with orthogonal frequenc…
Channel Training for Analog FDD Repeaters: Optimal Estimators and Cramér-Rao Bounds
Stefan Wesemann, Thomas L. Marzetta
For frequency division duplex channels, a simple pilot loop-back procedure has been proposed that allows the estimation of the UL & DL channels at an antenna array without relying…
Distributed Asynchronous Optimization Framework for the MISO Interference Channel
Stefan Wesemann, Gerhard Fettweis
We study the distributed optimization of transmit strategies in a multiple-input, single-output (MISO) interference channel (IFC). Existing distributed algorithms rely on stricly s…
