Study of Combining DVB-SH Signals from Satellite and Terrestrial Repeater

Hui Zhou
Abstract—In DVB-SH (Digital Video Broadcasting-Satellite services to Handhelds) systems, mobile terminals can receive either a signal from a broadcasting satellite or a signal from a terrestrial repeater. These two signals are not combined at the mobile receiver. The technique of signal combining is widely used in terrestrial mobile communication systems, and is effective against fading and multipath effects to improve the quality of received signals. Thus, the purpose of this paper is to discuss the feasibility of signal combining for DVB-SH terminals and to find out whether there is an improvement to be obtained by combining the signals from satellite and terrestrial repeater. In the paper, we first perform a statistical analysis of channels in different states. Then, we discuss two methods for combining the two signals. Finally, we analyze the improvement of each method.
