Abstract

In this paper, we address the problem of carrier frequency offset (CFO) estimation for Orthogonal Frequency Division Multiplexing (OFDM) systems with array antennas. We reconstruct the received signal to form data model with multi-invariance property, and then multi-invariance ESPRIT algorithm for carrier frequency offset estimation is proposed in this paper. This algorithm has the better CFO estimation than ESPRIT method and maximum likelihood method. Simulation results illustrate performance of this algorithm.
