The digital broadcasting services are expected to be more popular because of their high quality and bandwidth efficiency. In Japan, a digital broadcasting service was started with a broadcasting satellite (BS) in geostationary orbit at 110 degrees of east longitude. Previously, digital broadcasting services using communications satellites (CS) has already been introduced in Japan since June 1996. Today, services are provided with three satellites, JCSAT-3 (128°E) and JCSAT-4A (124°E) for SkyPerfecTV!. Since both BS and CS are operating at the 12-GHz band and the BS and CS receivers use similar blocks, we can reduce the total LSI size by using common components if the BS and CS receivers are implemented on the same LSI. This paper describes a VLSI demodulator architecture for both the digital BS broadcasting service based on ISDB-S (Integrated Services Digital Broadcasting Satellite) standard and the new digital CS broadcasting service based on DVB-S (Digital Video Broadcasting for Satellite) standard. We have also evaluated the LSI's performance with computer simulation and amount of hardware.
