METHOD TO TRANSFER DIGITAL INFORMATION BY SIGNALS WITH MINIMUM FREQUENCY MANIPULATION Russian patent published in 2013 - IPC H03C5/00 H04L27/10 

FIELD: radio engineering, communication.

SUBSTANCE: method to transfer digital information by signals with minimum frequency modulation is characterised by the fact that prior to implementation of minimum frequency modulation of carrier frequency, codes of modulation sequences of cophased and quadrature channels are generated, for this purpose information sequence designed for transfer is analysed in order to define the sequence order of odd and even single bits of information, procedure of distribution of zero bits of information, which follow odd bits of units, even and odd clock intervals are defined in the information sequence, generated codes of modulation sequences are converted into a bipolar code, and the minimum frequency modulation is carried out in two stages, besides, at the first stage sine and cosine harmonic oscillations of carrier frequency are phase-manipulated, and the period of the frequency is equal to fourfold duration of a unit element of transmitted information sequence.

EFFECT: production of manipulation sequences, which define one-to-one compliance of values of information message bits and nominals of frequencies designed for information transfer.
