METHOD OF BINARY INFORMATION TRANSMITTING AND RECEIVING OVER RADIO COMMUNICATION CHANNELS IN NON-AUTOMATIC MODE (VERSIONS) Russian patent published in 2016 - IPC H04L17/00 

FIELD: information technology.

SUBSTANCE: disclosed methods of binary information transmitting and receiving over radio communication channels in non-automatic mode under conditions of concentrated, noise and deliberate interferences relate to radio communication technique. Technical result consists in improvement of noise immunity and energy concealment of received information. Under conditions of concentrated and noise interferences disclosed is sequence of actions, which is displayed at receiving side with different slope gradients, not coinciding with gradient of lines, displaying concentrated interferences on spectrogram in "time-frequency" plane. Under conditions of deliberate interferences, using working frequencies intra-bit pseudorandom retuning mode with reduction of frequency chip duration to time, smaller than electronic countermeasures system response time, which enables to perform actual transition from channel with targeted deliberate interference to channel with random focused interferences, on background of which signal selection is carried out by visual identification of received binary packages, which visual image on spectrogram differs from interferences displaying by their slope gradients and other characteristics.

EFFECT: wherein disclosed methods noise immunity and energy concealment increasing depends not only on selected frequency range, radio channel state, noise level exceeding above signal level, but also on duration of binary packages, number of frequency chips used for their generation, as well as counteracting system capabilities.
