METHOD FOR SETTING UP COMMUNICATION BY MEANS OF NOISE-LIKE SIGNALS Russian patent published in 2006 - IPC H04B1/06 

FIELD: radio communications engineering, possible use for engineering communication systems with noise-like signals, primarily in satellite communication systems and communication systems with duplex channels.

SUBSTANCE: in accordance to method for setting up communications by means of noise-like signals, based on simultaneous emission of signal, consisting of a total of two synchronization series (SS1 and SS2) of multiple length, multiplication of received signal and signal of supporting SS1, shifted in time with step, equal to duration of elementary impulse, accumulation of result of multiplication, comparison of accumulated voltage to given threshold, on exceeding of which multiplication of input signal with supporting signal SS2 is performed, which is shifted in time with step, equal to duration of SS1 with following accumulation and comparison to threshold, after confirmation of setting of synchronization by SS2, SS1 is replaced by SS3, duration of which is divisible by duration of SS2, after setting of synchronization by SS3, SS2 is replaced by SS4, duration of which is divisible by SS3, process of replacement of SS is repeated until receiving required duration, and command for replacement of SS being emitted is transferred along reverse channel.

EFFECT: increased resistibility with little time needed for setting up communications.
