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. Chinese digital television terrestrial broadcasting standard recommends three kinds of Frame Head mode with PN420/PN595/PN945 as training sequences for the time domain synchronous OFDM (TDS-OFDM) based DTTB systems. At receiver side, Frame Head mode detection and symbol detection should be done before subsequent synchronization and channel estimation. In this paper, robust frame synchronization scheme is proposed for the Chinese TDS-OFDM-based DTTB systems. System performance studies under different channel situations are used to verify the efficiency of the proposed scheme.
