Abstract :
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 channel estimation scheme is proposed for the time domain synchronous OFDM (TDS-OFDM) based DTTB systems in the presence of phase noise. Simulations under different channel situations verify the efficiency of the proposed scheme.
