Abstract: This paper designs a transmitting system which is available in satellite communication. This system is based on Virtex-5 Field Programmable Gata Array(FPGA). It consists of PCI Express bus and optical communication module based on Aurora protocol. This system has the character of sending and receiving simultaneously for bidirectional I/O. Test result shows that the system achieves that the eight channels of PCI Express, and optical communication can works in real time data communication at a high-speed of 1.25 Gb/s. The system can effectively simulate the satellite data download as well as the remote control of the ground stations towards satellite.

Key words: Field Programmable Gata Array(FPGA), PCI Express protocol, optical communication, Direct Memory Access(DMA), satellite communication
