Abstract :
A joint propagation parameter estimation method for multicarrier systems is proposed. The main difference between single carrier and multicarrier models is outlined and handled in the derivation of the algorithm. The method uses a subspace-based 2D ESPRIT-like approach, exploiting frequency shift invariance of the system as well as the ULA geometry to provide closed-form estimation. Basic performance of the algorithm is illustrated through simulations and compared with respect to the Cramer-Rao bound
