Abstract

Communication with remote places is a challenge that in most cases is solved by means of satellites. However, for low-rate data transmission from remote sensors placed in Antarctic stations, this solution, a part from being too costly is of disadvantage since the geostationary satellite visibility is poor. In such scenarios, Skywave ionospheric communication systems represent a practical alternative to satellites. HF communications suffer from impaired propagation, i.e. long delay spread, medium Doppler values, high level of attenuation and high level of interference. To cope with some of these impairments, in this paper, a study of the time interleaving effect applied to OFDM symbols transmitted through a multipath time-varying long-haul ionospheric channel is studied.
