Abstract
The paper presents the results of the investigation of the adaptive algorithm for power amplifiers linearization. The basis for this algorithm is a method of adaptive inverse control of the objects such as ?black boxes?. Algorithm uses the Least Mean Square criterion. Computational procedures may be an alternative or complementation to LUT of amplifier input signal predistortion. The results of computer simulation confirm the efficiency of the proposed solution.
