Closed-form max-min power control for some cellular and cell-free massive MIMO networks
Lorenzo Miretti, Renato L. G. Cavalcante, Slawomir Stanczak +3
Many common instances of power control problems for cellular and cell-free massive MIMO networks can be interpreted as max-min utility optimization problems involving affine interf…
Unsupervised Learning of Adaptive Codebooks for Deep Feedback Encoding in FDD Systems
Nurettin Turan, Michael Koller, Samer Bazzi +2
In this work, we propose a joint adaptive codebook construction and feedback generation scheme in frequency division duplex (FDD) systems. Both unsupervised and supervised deep lea…
Limits of Transmit and Receive Array Gain in Massive MIMO
Tobias Laas, Josef A. Nossek, Wen Xu
In this paper, we consider the transmit and receive antenna array gain of massive MIMO systems. In particular, we look at their dependence on the number of antennas in the array, a…
Sign-Bit Shaping Using Polar Codes
Onurcan İşcan, Ronald Böhnke, Wen Xu
A new polar coding scheme for higher order modulation is presented. The proposed scheme is based on multi-level coding (MLC) with natural labeling, where the bit-level correspondin…
Finite-Precision Implementation of Arithmetic Coding Based Distribution Matchers
Marcin Pikus, Wen Xu, Gerhard Kramer
A distribution matcher (DM) encodes a binary input data sequence into a sequence of symbols with a desired target probability distribution. Several DMs, including shell mapping and…
On Reciprocity in Physically Consistent TDD Systems with Coupled Antennas
Tobias Laas, Josef A. Nossek, Samer Bazzi +1
We consider the reciprocity of the information-theoretic channel of Time Division Duplex (TDD) Multi-User-Multiple Input Multiple Output (MU-MIMO) systems in the up- and downlink.…
