  Abstract

In this letter, we investigate a beam placement problem to determine the optimal beam center position that maximizes the minimum transmission rate of users within a spot beam for low-Earth-orbit (LEO) satellite-based multicast services. We calculate the optimal beam center position through a geometric analysis with low complexity considering the high mobility of LEO satellites. The simulation results show that the proposed scheme optimally determines the position of the beam center within a short computation time and maximize the minimum rate of multicast users.
