Link Budget Analysis for New Satellite Telecommunications Systems: The MALTE Package
Abstract
Nowadays, the future satellite systems for telecommunications are designed to provide multimedia services similar to those offered by terrestrial infrastructures. The main objective in the design of such services is to provide a solution allowing the maximum data rate. This way, the authors propose a new tool, the MALTE package, to analyze accurately link budgets for new satellites operating in the Ka-Band (30 GHz/20 GHz) allocated for the Fixed Services. The use of this frequency band implies that new problems have to be understood and new challenges overcome: propagation phenomena affect more strongly the transmitted signals, and new technologies have to be developed. Moreover, in order to ensure a high capacity and availability of the transmission links, adaptive modulations and codes are used. In part 1, the paper recalls the classical method for link budget computation. In part 2, new systems based on adaptivity are shown. Finally, the last past introduces a new method based on a statistical approach in order to estimate accurately the spatial and temporal availability of the RF links.
