As part of the article the scientifically grounded synthesis of the algorithm of adaptive compensation of nonlinear distortion (ACNLD) of radio devices based on the use of the mathematical apparatus of a theory of nonlinear analysis (Voltaire series). Actual speed and accuracy of adaptation were determined by choosing the optimal value of transmission coefficient. Some actual causes of limitation of dynamic range and appearance of internal noises of radio equipment were established. The estimation of ACNLD noise influence on its efficiency was carried out, and also the influence of signal component of the reference input ACNLD on radio quality indicatorsDownloads
