A CDMA/PRMA Protocol for LEO Constellations
نویسنده
چکیده
In this paper the design of a multiservice MAC (Medium Access Control) protocol, as a candidate for the uplink communication channel for LEO constellations is proposed. The proposed scheme is just the combination of conventional PRMA protocol and CDMA techniques, which seems to be a very promising access method for the case of mixed voice/data traffic. A transmit permission technique based on Doppler frequency shift is also introduced, which results in reducing the multiple access interference level and hence, improves the performance of the system.

متن کاملTcp via Satellite Constellations
Many Transmission Control Protocol (TCP) versions have been proposed for terrestrial wired networks over the Internet Protocol (IP), e.g. Tahoe and Reno. TCP/IP is being studied to overcome its limitations within the satellite medium and to allow its efficient use in hybrid terrestrial/satellite networks. So far studies have been mainly directed to the use of Geostationary Earth Orbit (GEO) con...
