Digital Transmission Techniques for a Long Haul HF Link: DS-SS vs. OFDM
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 described the link in terms of availability, ignal-to-noise ratio, and delay and Doppler power profi...
