Frame Head Mode Detection for the Multiple-antenna Chinese DTTB System
To face the challenge of the high data throughput requirements for modern communications, extensive researches have been paid to broadband modulation. Multi-carrier modulation is one of the most important broadband modulation techniques. Orthogonal frequency division multiplexing (OFDM) is an effective multicarrier modulation technique for combating radio channel multipath fading and for high-bit-rate transmission over wireless channels and it is extensively used in modern digital television terrestrial broadcasting (DTTB) systems to support high performance bandwidth-efficient multimedia services. The technique of multiple antennas at the transmitter and at the receiver permits several fold increase in achieved data rates and spectral efficiency through spatial processing and the use of multiple transmit antennas and multiple receive antennas. The Chinese DTTB system with multipleantenna receiver is considered. 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 should be done. In this paper, a Frame Head mode detection scheme is proposed for the multiple-antenna receiver of the Chinese DTTB system. System performance studies under different channel situations are used to verify the efficiency of the proposed scheme.
