DVB-RCS2 emulation system: To verify system level functions for multiple terminals

This paper describes a emulation system design based on DVB-RCS2 standard and verification of several system level functions. The proposed system can provide the testing environments of real performance evaluation using hardware type Hub system and VSATs, and it supports a lot of virtual VSATs created by VSAT emulators to test the return link access control procedure. We used our emulation system to verify system level functions such as the access control, control burst assignment algorithm, RLE performance evaluation, and PEPSal performance verification. And we realized that this emulation system will be very useful to verify system level functions of satellite communication system until the system will be released to the market.
