FIELD: radio engineering.
SUBSTANCE: proposed programmable operating-frequency re-tuning (POFRT) radio link that can be used in POFRT communication systems in the environment of noise whose level periodically varies according to programmable re-tuning frequencies has newly introduced switching unit, frequency weighting coefficient shaping unit, and frequency analyzing unit. These newly introduced units make it possible for POFRT radio link to use frequencies with lower noise level more often and unfit frequencies are eliminated from re-tuning process.
EFFECT: enhanced noise immunity of radio link under transient noise impact.
