Abstract :
We introduce Advanced T-DMB system based on hierarchical modulation to increase data rate. As the requests for the mobile broadcasting services grow rapidly and become diverse, the technology competition among mobile broadcasting systems also becomes intense. For this, we developed the Advanced T-DMB system to satisfy various requests of viewers´ by increasing data rate of T-DMB maximally in double. The Advanced T-DMB keeps backward compatibility with the existing T-DMB. We developed the transmitter and receiver of the Advanced T-DMB, conducted LAB test and show the LAB test results and give concluding remarks.
