A new threshold switching scheme for a DVB-RCS+M return link in a terrestrian scenario

The new standard for DVB-RCS includes guidelines for mobile user in the market of aircraft, maritime and terrestrial. The standard suggests the possibility of using, in this scenario, a continuous carrier operation mode in the return channel beside the classical MF-TDMA mode. In this context it can be important a mechanism for switching between these two modalities in order to exploit in a better way the satellite resources. In this paper, after showing the typologies of applications considered in the simulation, a proposal of a novel switching mechanism is presented and the simulation results are reported in order to provide some guidelines to the satellite operators that want to adopt in their satellite system this hybrid mode.
