Leveraging von Mises Message-Passing for Massive MIMO Detection
Sweta Suresh, Arthur Michon, Charly Poulliat +2
Detection in massive multiple input multiple output (mMIMO) systems suffers from exponential complexity while using optimal decoders like maximum a posteriori (MAP). We propose a b…

Tensor-Based Modulation on the Unit Circle: A Coding Perspective
Sweta Suresh, Charly Poulliat, Claire Goursaud +1
Tensor-based modulation (TBM) provides a multi-linear spreading framework for blind multi-user separation in unsourced random access. In this paper, we show that TBM is a coded mod…

Channel Charting for Streaming CSI Data
Sueda Taner, Maxime Guillaud, Olav Tirkkonen +1
Channel charting (CC) applies dimensionality reduction to channel state information (CSI) data at the infrastructure basestation side with the goal of extracting pseudo-position in…
