This paper briefly describes the development background of the stable exciter to support the reliable AT-DMB field test. This exciter is designed and implemented as a hardware-based system, which includes core technologies such as hierarchical modulation and turbo coding. From verification of the exciter through the experiment, we confirm that the implemented exciter is suitable for the AT-DMB field...
In this paper, we briefly describe the AT-DMB transmission system and the hierarchical modulation scheme defined in it. After designing and implementing the T-DMB based hierarchical modulation platform, we also verify the AT-DMB system by constructing the experimental environment, which includes the AT-DMB prototype receiver, the AT-DMB signal analysis system, and the implemented platform. From the...
