• Computer filtering of images of ionograms of hf ionospheric radio communication paths and an algorithm for determining signal-to-noise ratio
  Published: 15.03.2018
  The algorithm of obtaining ionograms of oblique sounding of wideband radio channels was implemented in software. The paper presents an algorithm of c...
• DISPERSIVE DISTORTIONS OF SYSTEM CHARACTERISTICS OF BROADBAND TRANSIONOSPHERIC RADIO CHANNELS
  Published: 15.12.2017
  Modern radio systems that use a transionospheric channel, are required signal bandwidth expansion. However, with a significant bandwidth expansion, th...
• CLIENT-SERVER SYSTEM MOBILE EXPERIMENT CONTROL AND DATA ANALYSIS WITH OBLIQUE IONOSPHERIC SOUNDING
  Published: 14.12.2016
  We propose an approach to solving the problem of mobile management and the analysis of data of oblique sounding of an ionosphere and ionospheric HF...
• ALGORITHMS AND SOFTWARE OF WHITENing OF NOISE IN THE RECEPTION OF BROADBAND CHIRP SIGNALS IN THE HF COMMUNICATION CHANNEL
  Published: 14.12.2016
  Scientific substantiation of the adaptive noise whitening algorithm is given in the HF band when receiving a continuous chirp signal. The software i...
