Abstract :
The symmetric parallel factor analysis (PARAFAC) model has found numerous applications in array signal processing and communications. We derive the deterministic Cramer-Rao bound (CRB) for the symmetric RARAFAC model and illustrate the obtained results using an example with spatial signature estimation in sensor arrays.
