METHOD OF TRANSMITTING AND RECEIVING DIGITAL INFORMATION Russian patent published in 2010 - IPC H04L9/12 

FIELD: physics; radio.

SUBSTANCE: invention relates to radio engineering and specifically to information transmission in a communication network. The technical outcome is achieved due to that, at the transmitting side each message block is presented in form of a first number Y, which, using a hash function and a private key K and an initial vector v known at reception and transmission, is transformed to a second number Z with a considerably larger numerical interval than values of Y. The sequence of numbers Z is then transformed to a second sequence of digital numbers E, each of which is a prediction error which is then interpolated into an analogue signal E(t) and transmitted to a recipient. At the receiving side, the received signal E(t) is time-quantised to a second sequence of digital numbers E, which, using the same prediction as on the transmitting side, is converted to the sequence of second numbers Z, which is transformed to the sequence of first numbers Y via inverse transformation of the hash function. The obtained numbers Y are presented in form of a sequence of blocks, obtaining the transmitted binary information signal as a result.

EFFECT: improved electromagnetic compatibility inside a wireless communication system, improved information security of transmitted messages, possibility of operating with radio equipment of previous generations.
