Capacity allocation in a multi-transponder communications satellite with a common reconfigurable multiple-beam antenna
Abstract
A reconfigurable transmit multiple-beam antenna (MBA) connected to several nonlinear repeaters is used as a means of resource allocation in a communications satellite serving the traffic requirements of different types of users and earth terminals. System performance objectives for the adjustment of MBA gains and carrier powers are determined by taking into account realistic up-link, repeater and down-link noise contributions. The results are demonstrated using a numerical example which considers two repeaters with different characteristics sharing a common MBA.
