Abstract:
In this paper, we introduce narrowband uplink transmission scheme to adapt orthogonal frequency division multiple access scheme to satellite environments. Maximizing the commonalities with the terrestrial system is one the most important factors for cost-effective service delivery, which will finally bring successful deployment of the system. For this purpose, we adopt an orthogonal frequency division multiplexing based radio interface. At the same time, the interface should be tailored in order to be operable in a power limited uplink scenario of satellite systems. In this paper, we present a narrowband uplink transmission, which was developed for this purpose, in long term evolution based satellite radio interface. Simulation results show that the proposed scheme can increase an uplink spectral efficiency at power-limited handheld terminal.
