A network architecture for a geostationary communication satellite

Applications Of Antenna Arrays To Mobile Communications, Part I: Performance Improvement, Feasibility, And System Considerations

“…Some network architecture and traffic-implication issues of mobile communications in general are considered in [48] and [171]- [173]. However, there is no consideration of the complications arising from the use of an array in such systems.…”

Description and simulation of a fast packet switch architecture for communication satellites

“…These systems are geared toward applications requiring data rates of 1.544/2.048 Mb/s. 1 NASA envisioned a need for a meshed-VSAT system that would provide low data rate capability for interactive data, voice, facsimile and video conferencing applications. Such a network would have to be capable of single-point and multicast (multiplepoint) transmission, while still being competitive with existing terrestrial communication systems.…”

“…Such a network would have to be capable of single-point and multicast (multiplepoint) transmission, while still being competitive with existing terrestrial communication systems. 1 The multichannel communications signal processing satellite (MCSPS) architecture, shown in Fig. 1, is based on a multifrequency, time-division-multiple-access (MF-TDMA) uplink and a time-division multiplex (TDM) downlink.…”

“…The advantages of this architecture are discussed in a previous paper. 1 As Fig.1 shows, the information-switching processor (ISP) is the most important subsystem in the architecture. This portion of the MCSPS was developed and simulated in-house by using VHSIC Hardware Description Language (VHDL).…”

“…To greatly reduce the amount of onboard memory storage required, the system is designed to use a subpacket scheme, 1 as shown in Fig. 2.…”
