Abstract

An adaptive power allocation method for signals transmitted from high-altitude platforms is proposed, and justification of its usefulness is provided. The possible structural scheme for the system is given and its performance is investigated. The adaptation algorithm is based on an optimization procedure, which enables the allocation of the available power to a maximal number of users. The proposed algorithm is tested on simulations. It is shown that for Nakagami fading in downlink channels, the adaptive power allocation yields an energetic gain which can attain up to 21 dB.
