Abstract. A model of noise-immune signal construction is developed to improve the efficiency of data transmission by radio control and measuring complexes. The proposed construction is based on a hexagonal structure and 4-way quadrature modulation. The use of amplitude and phase balanced modulation is shown to increase the spectral efficiency of the signal construction. A device is implemented for the developed model realization.
Keywords: noise immunity, spectral efficiency, signal design
