초록

In this paper, we introduce Satellite Digital Multimedia Broadcasting(S-DMB) system and show the method increasing the channel capacity. To reduce the burden that has to change the existing system, the system has to be offered the Backward-compatibility. This paper show the method using hierarchical 16APSK modulation. And to obtain the reasonable BER performance between existing path(we call high priority) and additional path(we call low priority).
