FIELD: radio engineering, communication.
SUBSTANCE: invention relates to communication equipment and can be used for mobile communication systems receiving broadband signals. A user device receives a broadcast channel transmitted from a basic station for the pre-set number of times in a pre-set cycle. The user device includes a receiving module and a processing module having the possibility of processing the received broadcast channel. The latter is one of scrambled broadcast channels received by repetition of a broadcast channel for the pre-set number of times to form a set of broadcast channels and scramble the formed broadcast channels by means of different scrambling codes, the number of which is equal to the specified number of times.
EFFECT: improvement of interference immunity by using transmission channel scrambling.
