This work deals with the problem of carrier-frequency offset estimation in orthogonal frequency-division multiplexing-based cognitive radio systems. In particular, we propose an iterative algorithm which provides frequency estimates in closed form without involving any computationally demanding grid-search. Computer simulations are used to assess the effectiveness of the proposed solution and to make comparisons with existing alternatives.

Abstract
This work deals with the problem of carrier-frequency offset estimation in orthogonal frequency-division multiplexing-based cognitive radio systems. In particular, we propose an iterative algorithm which provides frequency estimates in closed form without involving any computationally demanding grid-search. Computer simulations are used to assess the effectiveness of the proposed solution and to make comparisons with existing alternatives.File in questo prodotto:
