“…The recovery processing contains the carrier recovery and symbol timing recovery, and the algorithms are the same as used in legacy 8-VSB receivers [3] [4]. When the carrier recovery is performed at the demodulator, frequency offset information can be obtained by measuring the frequency differences between the pilot carrier and the Numerically Controlled Oscillator (NCO).…”

In this paper, a frequency synchronization technique for the Equalization Digital On-Channel Repeater (EDOCR) in ATSC System is proposed and the proposed algorithm is verified by mathematical analysis. The proposed algorithm uses the frequency offset information that comes from carrier and symbol timing recovery in the receiving part of EDOCR when the demodulated symbol is re-modulated in transmitting part. Therefore, the algorithm makes it possible for the EDOCR output signal to synchronize with input signal in frequency without additional reference source. Also, the synchronized EDOCR output does not degrade the reception performance of legacy receivers.

This chapter provides a summary of a Digital TV (DTV), from a signal processing point of view. After an overview of DTV, video and audio compression are covered. This is followed by multiplexing of the video, audio and data signals to form a transportation stream. In order to be able to receive a digital signal, forward error correction is required. The next step in preparing a signal for transmission is to modulate it. Orthogonal Frequency Division Multiplexing (OFDM) is used in DTV systems. The benefits of OFDM are discussed. The signal path in a receiver is briefly covered, as well as a summary of trends in television receiving platforms.
