Abstract :
The DoD joint internet protocol modem is based on the digital video broadcast (DVB) standard. In a star network topology the forward traffic is DVB-Satellite 2 (DVB-S2) and the return traffic is DVB-return channel by satellite (DVB-RCS). The joint modem adds an embedded TRANSEC capability and a mesh overlay allowing user terminals to communicate without passing through the hub. The analysis will take advantage of the variable coding and modulation (VCM) feature [as well as the constant coding and modulation (CCM) feature of DVB-S]. First, the DVB-S2 capacity will be determined for wideband gapfiller satellite (WGS) located at 175deg east using a set of reference links located in Korea using CCM and VCM in the forward direction. Then the capacity of WGS will be determined in the return direction using DVB-RCS. Finally, the mesh capacity will be determined using WGS with VSAT terminals (1m) in Korea for voice over internet protocol (VoIP) traffic
