Outage probability of an adaptive TDMA satellite access scheme

An adaptive TDMA satellite access scheme able to counteract rain attenuation effects is sketched together with the employed prototypes of satellite controller and burst modem. The resulting system, based on the shared resource philosophy, is usable to support a multiplicity of applications in a LAN interconnection environment. Faded links are assisted by choosing the bit rate, the coding rate and the transmitting power level according to the fade level to be countered. A Monte Carlo Simulation of the system behaviour has carried out to compute the outage probability of each link when operating in Ka band on the Olympus satellite. The shared resource occupancy has also been investigated. Comparisons are made with systems of the same capacity and without any fade countermeasure.
