The formative stages of the minimum frequency manipulation with a continuous phase with a modified algorithm of formation of quadrature components and Barker code encoding are discussed in this article. The results of modelling the digital sequences scheme using this method are presented. The method of minimum frequency manipulation with continuous phase with changed algorithm of quadrature components formation and Barker code encoding has been described earlier. The minimal spreading of frequencies for minimum frequency manipulation by which the orthogonality of opposite signals is still maintained, it is implemented when the manipulation index is m = 0.5 and constitutes the value that is inversely proportional to the doubled duration of the elementary pulse transmitted by the sequence, 2Δf = 1/2τ.
