A heuristic approach to worstcase carriertointerference ratio maximization in satellite system synthesis
Abstract
Consideration is given to the problem of allotting GEO locations to communication satellites so as to maximize the smallest aggregate carriertointerference (C/I) ratio calculated at any test point (assumed earth station). The location allotted to each satellite must be within the satellite's service arc, and angular separation constraints are enforced for each pair of satellites to control singleentry EMI. Solutions to this satellite system synthesis problem (SSSP) are found by embedding two heuristic procedures for the satellite location problem (SLP), in a binary search routine to find an estimate of the largest increment to the angular separation values that permits a feasible solution to SLP and SSSP. Numerical results for a 183satellite, 208beam example problem are presented.
