This paper intends to introduce widely the broadcasting satellite services using Digital System E of Recommendation ITU-R BO.1130. The system is designed to provide high-quality audio and multimedia and data broadcasting services to mobile receivers, handheld and vehicular. The geostationary satellite specially designed for this system was launched successfully in March 2004, followed by the inauguration of regular broadcasting services on 20 October 2004. Due to the nature of satellite broadcasting, it covers the Japanese area widely. The system also adopts complementary terrestrial on-channel repeaters for shadowed areas from the direct satellite broadcasting signal. It should be noted that the system is the world first broadcasting satellite services for handheld and vehicular receivers with high-quality audio and multimedia and data receiving capability.

In this paper, we propose a new improved interleaver that shows very robust performance under the condition of adding any periodic errors at the input of the deinterleaver. In the S-band digital mobile satellite broadcasting system, periodic errors at the input of deinterleaver will be occurred when the vehicle runs through between two GFs at strictly constant speed maintaining exactly the same distance from two GFs. Our results using a transmission simulator show that the BER performance of the proposed scheme is superior to that of the conventional periodic interleaver when adding the periodic errors at the input of the deinterleaver. Also, it satisfies a few important characteristics of the conventional periodic interleaver.
