Abstract :
In this paper, a method to improve the link quality of a satellite TDMA network using adaptive resource sharing is presented. The TDMA network considered is an experimental 20/30 GHz satellite network operated via the German satellite DFS KOPERNIKUS. Adaptive resource sharing provides a means to distribute a common resource within a network. The common resource in a TDMA system is an additional time slot. This spare time is used for lowering the code rate and/or the data rate. This results in better link quality and/or better link availability. Another resource used is the uplink transmit power to compensate for uplink fades. This paper describes the adaptive resource sharing strategy and the uplink power control implemented in the experimental 20/30 GHz TDMA satellite network
