The harmonic Minimum Shift Keying modulated signal energy spectrum is found, which phase paths are smoothed by function, where T the duration of the elementary package. Noise- immunity of optimal receiving of such signal against a white noise is defined. Comparing classical and harmonic Minimum Shift Keying modulated signals by spectral efficiency and noise-immunity is executed.
