Annotation: In the article, the algorithm to calculate channel coefficients of the power method in non-orthogonal multiple access is proposed. The algorithm allows to calculate the power factor on the basis of a priori information about the channel of distribution and a request for provision of bandwidth. The results of the mathematical calculation of power factors for multiple scenarios organization of communication channel are shown. The calculation results revealed that the non-orthogonal multiple access method provides a better maximum channel capacity than orthogonal multiple access method.
