Abstract
This paper presents an algorithm for joint estimation of carrier frequency offset and timing frequency offset in orthogonal frequency division multiplexing (OFDM) systems. A weighted least squares algorithm based on a pilot-aided scheme is proposed. The algorithm operates near the Cramér-Rao bound in the variance of estimation errors. Simulations of several estimation algorithms in a multipath fading channel show that this algorithm provides the most accurate estimation in both the carrier frequency offset and the timing frequency offset.
