Abstract :
In this paper, we propose an Augmented Data Transmission (ADT) system which can transmit an additional data stream in the ATSC terrestrial DTV system. The proposed ADT system can offer an additional data of rate up to a few Mbps based on hierarchical modulation, DTV signal cancellation, and advanced error correction code. Since the proposed ADT system uses the in-band hierarchical modulation, it does not require any additional RF spectrum to increase the data capacity in a 6 MHz RF channel.
