Reverse Ordering Techniques for Attention-Based Channel Prediction

no code implementations1 Feb 2023 Valentina Rizzello, Benedikt Böck, Michael Joham, Wolfgang Utschick

This work aims to predict channels in wireless communication systems based on noisy observations, utilizing sequence-to-sequence models with attention (Seq2Seq-attn) and transformer models.

Variational Inference Aided Estimation of Time Varying Channels

no code implementations31 Oct 2022 Benedikt Böck, Michael Baur, Valentina Rizzello, Wolfgang Utschick

One way to improve the estimation of time varying channels is to incorporate knowledge of previous observations.

Learning Representations for CSI Adaptive Quantization and Feedback

no code implementations13 Jul 2022 Valentina Rizzello, Matteo Nerini, Michael Joham, Bruno Clerckx, Wolfgang Utschick

In this work, we propose an efficient method for channel state information (CSI) adaptive quantization and feedback in frequency division duplexing (FDD) systems.
