초록
In this paper, we propose a novel augmented data transmission (ADT) system based on low density parity check (LDPC) code for an additional data stream transmission in the Advanced Television Systems Committee (ATSC) terrestrial digital television system. The LDPC code-based ADT system can provide additional data of rate up to 3 megabits per second (Mbps), which is significantly improved over the conventional data transmission schemes used in the transmitter identification system. Based on the laboratory test, we verify that the LDPC code-based ADT system is only about 1.1 dB away from Shannon limit. © 2012 IEEE.
