Spread spectrum satellite multiple access and overlay service
… applications of spread spectrum technology to very small aperture terminal (VSAT) satellite communication networks. It describes two spread spectrum multiple access systems which use a form of noncoherent M-ary FSK (MFSK) as the primary modulation and analyzes their throughput. The analysis …

Performance analysis of VSAT networks
Very small aperture terminal (VSAT) networks offer a solution to the increasing demand for low-density voice and data communications. Spread Spectrum and single-channel-per-carrier (SCPC) transmission techniques work well for multiple access purposes while allowing the earth station antennas to …

Analysis and design of a data network for distance education for the state of Virginia
… from Blacksburg to all distant class sites. A very good 19.2 kbps carrier is available with bit error rate (BER) of 1E-6 or less. A very small aperture terminal (VSAT) network has also been proposed for the purpose.

Performance analysis of star architecture packet-switched VSAT network using roll-call polling multiple access scheme
… This study analyses the performance of a Very Small Aperture Terminal (VSAT) satellite star network. The network uses roll-call polling as its multiple access scheme, High-level Data Link Control or HDLC, and go-back-N Automatic Repeat Request, for error control. The network is a VSAT …

Performance analysis of star architecture packet-switched VSAT networks using random code division multiple access
… of multiple access protocols in packet-switched Very Small Aperture Terminal (VSAT) satellite communication networks. This research consisted of three major thrusts. First, we analyzed the average time delay of the broadcast Time Division Multiplexing (TDM) outbound channel (hub to VSAT). Second, …

An educational VSAT system for Thailand
Very small aperture terminal (VSA T) networks offer great opportunities to combine satellite technology and the needs of education in Thailand. An educational VSAT network for Thailand needs a central hub station in Bangkok and seven remote sites with VSAT equipment. The network supports two way …
