A comprehensive sounding of the ionospheric HF radio link from Antarctica to Spain
Ads, Ahmed Gamal; Bergadà Caramés, Pau; Vilella Parra, Carles; Regué, Joan Ramon; Pijoan Vidal, Joan Lluís; Bardají Benach, Raúl; Mauricio Ferré, Juan (Radio Science, 2013. Vol.48, 1, Gener - Febrer, 2013-01)Since 2003, our group has been investigating the performance of different transmission techniques for low-power low-interference High Frequency (HF) ionospheric communication systems. Specifically, we ... -
Digital Transmission Techniques for a Long Haul HF Link: DS-SS vs. OFDM
Bergadà Caramés, Pau; Alsina Pagès, Rosa Maria; Pijoan Vidal, Joan Lluís; Salvador Marín, Martí; Regué, Joan Ramon; Badia Folguera, David; Graells Castellà, Simó (Radio Science. 2014, Vol.49, No.7 (Juliol), 2014-06)This paper presents two digital transmission techniques for long haul ionospheric links. Since2003 we have studied the HF link between the Antarctic Spanish Base, Juan Carlos I, and Spain; and wehave ... -
Low Rate High Frequency Data Transmission from Very Remote Sensors
Bergadà Caramés, Pau; Alsina Pagès, Rosa Maria; Vilella Parra, Carles; Regué, Joan Ramon (Remote Sensing - Advanced Techniques and Platforms, 2012-06)This chapter deals with the difficulties of transmitting data gathered from sensors placedin very remote areas where energy supplies are scarce. The data link is established bymeans of the ionosphere, ... -
Remote Sensor Data Transmission from Antarctica to Spain with a Long-Haul HF Ionospheric Link
Alsina Pagès, Rosa Maria; Badia Folguera, David; Bergadà Caramés, Pau; Hervás García, Marcos; Orga Vidal, Ferran; Pijoan Vidal, Joan Lluís; Regué, Joan Ramon; Salvador Marín, Martí; Altadill Felip, David (2015)The geophysical observatory in the Antarctic Spanish Station Juan Carlos I (BAE), on Livingston Island (62.6S, 60.4W), has been monitoring the magnetic field in the Antarctic region for more than fifteen ... -
Vertical and Oblique ionospheric soundings over the long haul HF link between Antarctica and Spain
Ads, Ahmed Gamal; Bergadà Caramés, Pau; Regué, Joan Ramon; Alsina Pagès, Rosa Maria; Pijoan Vidal, Joan Lluís; Altadill Felip, David; Badia Folguera, David; Graells Castellà, Simó (Radio Science. 2015, Vol. 50, No.9 (Setembre), 2015-09)This paper presents a comparative study between the oblique sounding results, theInternational Telecommunication Union Rec533 HF prediction model, and the vertical sounding results of atransequatorial ...
