The FODA-TDMA satellite access scheme: Presentation, study of the system, and results

A description is given of FODA-TDMA, a satellite access scheme designed for mixed traffic (patent N. 9373A/89). The study of the system is presented and the choice of some parameters is justified. A simplified analytic solution is found, describing the steady-state behavior of the system. Some results of the simulation tests for an already existing hardware environment are also presented for the channel speeds of 2 and 8 Mb/s, considering both the stationary and the transient cases. The results of the experimentation at 2 Mb/s on the satellite EUTELSAT-F2 are also presented and compared with the results of the simulation.
