As an effective technique for combating multipath fading and for high-bit-rate transmission over wireless channels, orthogonal frequency-division multiplexing (OFDM) is extensively used in modern digital television terrestrial broadcasting (DTTB) systems to support high performance bandwidth-efficient multimedia services. In this paper, a robust phase noise suppression scheme is proposed for the time domain synchronous OFDM (TDS-OFDM) based DTTB systems. Simulation results under different channel environments are presented to illustrate the effectiveness of the proposed scheme.
