Design and implementation of hierarchical modulation platform for advanced T-DMB services

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 experimental result, we present the technical possibility of new T-DMB based AT-DMB system and service.
