METHOD OF TRANSMITTING INFORMATION WITH INTRA-SYMBOL PSEUDORANDOM OPERATIONAL FREQUENCY USING RANDOM SIGNALS Russian patent published in 2016 - IPC H04L9/20 

FIELD: radio engineering and communications.

SUBSTANCE: invention can be used in data transmission systems with higher requirements to reconnaissance-protection and protection against organised and unintentional interference. For this purpose, signal power is distributed in band associated both with carrier frequency adjustment and using random signals. At that, chaotic signals are not repeated from character to character. Besides, there is separation of symbols into independent frequency elements, each of which is transmitted to its frequency in accordance with given pseudorandom sequence, wherein each frequency element is fragment of one of specified set of chaotic signal.

EFFECT: high information transmission speed in comparison with classical system with pseudorandom operating frequency, as well as high reconnaissance protection.
