This paper considers the problem of SFO estimation for OFDM-based digital radio mondiale (DRM) systems. In this study, we develop expressions for the mean square error (MSE) of the conventional SFO estimators used in the OFDM-based DRM system. Their low-complexity variants and computation complexity are reported. The theoretical MSE analysis for different algorithms are validated by Monte-Carlo simulations within the framework of the OFDM parameter and pilot pattern defined in the DRM specification. It is also shown that the computation complexity of the low-complexity variants is significantly reduced, compared with that of original versions.
