Multipath measurements in the Athens-Salisbury T.E.P. link
Abstract
The propagation times of radio pulses in a 6250-km, 34.0-MHz Trans-Equatorial Propagation (TEP) link between Athens, Greece, and Salisbury, Zimbabwe, is studied experimentally, using the forward-propagation pulse technique, and by computer simulation, using a ray-tracing program and plausible models for the propagation medium. This comparative method is shown to be efficient in determining the dominant mode in the type of propagation, and explains the doubling observed in TEP received pulses during multipath conditions. The results presented may prove useful in an attempt to apply pulse code modulation techniques in communications via TEP.
