T-DMB (Terrestrial Digital Multimedia Broadcasting) system, is based on the Eureka-147 standard, provides various multimedia data services. However TDMB needs more various services and higher throughput while maintaining reception. Therefore, this paper proposes advanced T-DMB system using the unequal error protection system, hierarchical multi level modulation and various coding scheme which is used for recent wireless communication, while maintaining backward compatibility. As the simulation results, proposed advanced T-DMB system has coding gain of 2~6㏈ compared to conventional T-DMB.
