Abstract: Abstract:In this paper, we propose a power assignment mechanism in Ka band orthogonal frequency division multiplexing (OFDM)-based multi-satellites mobile telemedicine. The mobile telemedicine system considers the employment of OFDM techniques, multi-satellites transmission architectures, space time block code (STBC) strategies, direct map (DM) strategies, power assignment mechanisms, unequal error protection mechanism, channel estimation, and adaptive modulation schemes in a Ka band. Simulation results show that the proposed scheme can not only fulfill the quality of services (QoS) required by a mobile telemedicine system, but can also achieve maximum transmission bit rates as well as minimum transmission power.
