Future communication systems are to be designed to support and serve multimedia and multiple data transmission. Nowadays, requirement of mobile subscribers for the various information such as movie, GPS (Global Positioning System) information, news-is increasing significantly. However, due to practical reasons, the capacity and number of capable channels are limited. To solve this problem, a large number of methods and schemes have been proposed and are under research. In this paper, we demonstrate how satellite DMB (Digital Multimedia Broadcasting) system works with hierarchical modulation scheme. By using hierarchical modulation, we can analyze the capacity. Meanwhile, system performance is evaluated and compared to conventional DMB system without using hierarchical modulation.
