SIGNAL-CODE CONSTRUCTS AND PROCESSING ALGORITHM WITH AUTOMATIC DISPERSION DISTORTION COMPENSATION FOR WIDEBAND HF COMMUNICATION
Nikolay A. Kandaurov, MTUCI, Moscow, Russia, kandaurov@srd.mtuci.ru
Abstract
HF communication is a backup form of communication, especially in demand in emergencies in remote areas. Basically it is necessary to send short text messages, but over long distances. The disadvantage is the dependence of the quality of radio communications in different frequency ranges on the state of the ionosphere and the workload of the decameter range by powerful broadcasting stations. The solution to the problem is the use of wideband noise-like signals and complex signal-code constructs. When using wideband signals in HF communication, frequency dispersion has a significant effect on the signal.
Keywords: signal-code constructs, ionosphere, dispersion distortion, HF communication, wideband.
