This paper considers the problem of Sampling Frequency Offset (SFO) estimation for Orthogonal Frequency Division Multiplexing (OFDM) based Digital Radio Mondiale (DRM) systems. In this paper, the Mean Square Error (MSE) expression for conventional SFO estimators is derived and their low-complexity variants are reported. The theoretical MSE analysis for different algorithms are validated by Monte-Carlo simulations and proven accurate. OFDM is already used in the broadcasting domain, such as Digital Audio Broadcasting (DAB), Digital Radio Mondiale (DRM), and Terrestrial Digital Video Broadcasting (DVB-T).
