METHOD FOR TRANSMITTING AND RECEIVING DISCONTINUOUS INFORMATION WITH PSEUDO-RANDOM SIGNALS Russian patent published in 2006 - IPC H04L9/12 

FIELD: radio engineering, possible use for increasing structural and informational concealment of digital signal being transmitted, and also for increasing resistance of radio communication systems to interference.

SUBSTANCE: in the method for transmitting and receiving discontinuous information with pseudo-random signals computation of autocorrelation functions of input pseudo-random signals is performed during time, equal to duration of code combination τ_k, resulting in n times increased signal/noise ratio at output of correlators, while information message itself is not transmitted via radio line. In the method for transmitting and receiving discontinuous information with pseudo-random signals, signals of binary code combination by means of encoder are transformed to signals of encoded code combinations, then to each encoded code combination appropriate pseudo-random signal number is assigned, and combinations are transmitted via radio channel at bearing frequency during time, equal to its duration τ_k, while receipt and processing of these pseudo-random signals is performed by means of correlators, number of which is equal to number of pseudo-random signals being transmitted with processing time of each one being equal to duration of code combination τ_k, as a result of which video impulses are generated, by means of which from memory device appropriate encoded code combinations are read, which are transformed by decoder to code combinations of digital signal being transmitted in accordance to provided encoding rule, which are then added together and digital signal being transmitted is produced at output of receiving device.

EFFECT: increase resistance of digital signal receipt to interference, and also increased informational and structural concealment.
