Abstract
In this paper, we describes about implementations of Advanced Terrestrial DMB prototype system which can provide high higher efficiency of transmission and better quality of service than Terrestrial DMB(T-DMB) system for performance improvement of conventional mobile multimedia broadcasting system. And also we analyze field test results of the system. Advanced T-DMB system has been developed to increase data rate up to double of conventional T-DMB in same bandwidth while maintaining backward compatibility, using hierarchical modulation and turbo code. We conducted field tests to verify the performance of the proposed system through implementing of test system. As a result, we confirmed 0.576Mbps and 1.152Mbps were added to mode B and mode Q of Advanced T-DMB respectively than T-DMB system.
