dc.description.abstractThis 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 described the link in terms of availability, ignal-to-noise ratio, and delay and Doppler power profile.Based on these previous studies we have developed a test bed to investigate two digital transmissiontechniques, i.e., Direct-Sequence Spread Spectrum (DSSS) and Orthogonal Frequency Division Multiplexing(OFDM), which can provide a low power, low-rate ionospheric data link from Antarctica. Symbol length,bandwidth, and constellation are some of the features that are analyzed in this work. Data gathered from thelink throughout the 2010/2011 and 2011/2012 Antarctic surveys show that the spread spectrum techniquescan be used to transmit data at low rate when the channel forecast is poor, but when the channel forecastis good multicarrier techniques can be used to transmit sporadic bursts of data at higher rate.eng
