Thesis Description

This project explores the application of flow matching — a recent generative modeling framework — to wireless physical layer tasks. Many key problems in wireless communication, such as channel estimation and MIMO detection, can be formulated as inverse problems, where the goal is to reconstruct the transmitted signal or channel state information from noisy and incomplete observations.

By leveraging flow matching, we aim to learn data-driven vector fields that transform simple prior distributions into the complex distributions of wireless channels and transmitted signals. This approach offers several advantages:

• Provides a probabilistic generative model of the channel and signal space.
• Allows solving inverse problems by learning transport maps instead of hand-crafted estimators.
• Scales naturally to high-dimensional problems such as massive MIMO and OFDM-based systems.

The ultimate goal is to demonstrate that flow-matching-based solvers can outperform or complement classical estimators in terms of robustness, accuracy, and generalization across diverse channel conditions.
