HDTV TRANSMISSION EXPERIMENT USING N-STAR

The Communications Research Laboratory (CRL) is aiming to develop giga bit satellite communication systems for the global information infrast ructure (GII). As a first step, CRL planned high data rate (HDR) satel lite communications experiments using the Japanese Engineering Test Sa tellite-VI (ETS-VI). ETS-VI failed to reach a geostationary orbit, how ever, and CRL then decided to use the NTT satellite known as N-Star fo r the HDR satellite communications experiment. In this experiment, we planned a data rate of 156 Mbps through a Ka-band transponder with a b andwidth of 200 MHz. Data was transmitted as an HDTV signal in our pla n. In this paper, we introduce the configuration of this experimental system and the experimental items. Our next application experiment pla ns are also explained.
