Improved additional data transmission based on low density parity check code for the ATSC terrestrial DTV systems
Heung Mook Kim, Sung-Ik Park, Jeongchang Kim · 2012
This paper proposes an improved additional data transmission (ADT) system based on low density parity check (LDPC) code which can transmit an additional data stream in the Advanced Television Systems Committee (ATSC) terrestrial digital television system. The LDPC code based ADT system can offer an additional data of rate up to a few megabits per second (Mbps) which is significantly increased compared to the conventional data transmission schemes used in the transmitter identification system.
