摘要: Several candidate crosslink communications architectures are described for a packet-switched, low-altitude, multiple satellite system (MSS). One architecture represents frequency-division approach, in which cellular concept is combined with dynamic time-domain allocation within cell. A second uses an unsynchronized space-time division approach consisting of directional antennas and random accessing. third toroiclal The recommended synchronized contention-based pair-wise scheduling. This architecture, called PRS (Pseudo-random Scheduling) found to have significantly reduced power bandwidth requirements relative the other approaches.
