Uncertainty Propagation in the Fast Fourier Transform
Luca Schmid, Charlotte Muth, Laurent Schmalen
We address the problem of uncertainty propagation in the discrete Fourier transform by modeling the fast Fourier transform as a factor graph. Building on this representation, we pr…

Optimization of Iterative Blind Detection based on Expectation Maximization and Belief Propagation
Luca Schmid, Tomer Raviv, Nir Shlezinger +1
We study iterative blind symbol detection for block-fading linear inter-symbol interference channels. Based on the factor graph framework, we design a joint channel estimation and…

Local Message Passing on Frustrated Systems
Luca Schmid, Joshua Brenk, Laurent Schmalen
Message passing on factor graphs is a powerful framework for probabilistic inference, which finds important applications in various scientific domains. The most wide-spread message…
