An antarctica to Spain HF Link. Oblique sounding results

Our Research Group in Electromagnetism and Communications is involved in a project dealing with the channel characterization and data transmission from the Spanish Antarctic Base (62.6S, 60.4W) to Spain (40.8N, 0.5E). In this paper the results of the third sounding survey corresponding to 22 consecutive days from January to February 2006 are presented. Frequencies in the range from 4 to 18 Mhz, and bandwidths up to 16.5 Khz have been probed. Results in terms of propagation losses, delay and Doppler spreads and signal to noise and interference ratio are summarized.
