A Novel Adaptive Reception Technique for Satellite-DMB systems in a Rician Channel

Abstract

Satellite-Digital Multimedia Broadcasting (S-DMB) systems make it possible to watch the televisions on the hands as well as in the vehicular outside. But in case of handheld version of terminal, especially S-DMB phone, there are several challenging issues, which have not been seen in the other terminals. One of these issues is short viewing time, which is caused by limited battery. In this paper, we propose an Adaptive Reception Technique (ART) which provides power saving when the line-of-sight path exists from the satellite. By launching the Frame Selection Control (FSC) at the receiver and modifying the puncturing algorithm, we can simply employ ART and reduce power consumption by about 17.5∼25.5%/.
