FIELD: radio engineering, communication.
SUBSTANCE: transmitter with code division of channels, known from patent No2287904, further includes a frequency divider, a nonlinear masking sequence generator, a nonlinear orthogonal code generator, and each channel circuit includes an internal encoder and a channel signal spectrum generator and corresponding connections thereof in order to form a novel signal-code structure and implementing secure synchronisation in a communication system, which significantly increases structural security of transmitted signals.
EFFECT: high structural security of signals in advanced communication systems.
