The integrated services digital broadcasting-terrestrial (ISDB-T) system is designed to individually configure transmission parameters of each orthogonal frequency division multiplexing (OFDM) segment using band segmented transmission OFDM (BST-OFDM). Since the pilot configuration relies on whether a segment is a differential or coherent modulation, it is important to develop the frequency-offset estimation scheme that conforms to the segment-dependent pilot structure in the BST-OFDM system. This paper proposes an efficient sampling frequency offset (SFO) in the ISDB-T system using BST-OFDM. Extensive simulations are conducted not only to verify the effectiveness of the proposed SFO estimation scheme but also to compare the new scheme with the conventional scheme. It has confirmed that the performance of the proposed SFO estimation algorithm is better than that of the existing algorithm at a reduced computational cost.
