摘要：
This paper proposes a robust residual carrier frequency offset (CFO) tracking scheme with an extended estimation range, as well as an improved estimation performance in a multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) system. An analytical expression for the mean square error (MSE) of the frequency synchronization scheme is reported, and simulation results are used to verify the theoretical analysis developed in this paper.
