APPARATUS FOR SYNCHRONISING PSEUDORANDOM SEQUENCE FOR COMMUNICATION SYSTEMS WITH MULTIFREQUENCY SIGNALS Russian patent published in 2016 - IPC H04W56/00 

FIELD: information technology.

SUBSTANCE: invention relates to transmission of discrete information and can be used for synchronisation of pseudorandom sequences. Device consists of series-connected first switch, linear recurrent feedback register (LRR), comparator unit, as well as a second switch, output and input of which are connected with input and output of feedback register, other output of which is connected to input of decoder, wherein to input of first switch and other input of comparator unit is transmitted a signal from output of unit of decision device, to parallel inputs of which is supplied a pseudo-random sequence from subchannels, as well as an error counter and a pulse counter, output of which is connected to second inputs of first and second switches.

EFFECT: technical result is improvement of accuracy of synchronisation of pseudorandom sequences in communication systems with multifrequency signals and higher probability of preventing premature switching of synchronisation system from independent in channel synchronisation mode with rising jamming in a communication channel.
