FIELD: radio engineering, communication.
SUBSTANCE: device and method are proposed to transfer a preamble in a DVB system, at the same time the device comprises: the first processor for generation of a modulation signalling sequence (MSS) with application of multiple received sequences and for production of a modulated sequence by means of differential modulation MSS; a scrambling module for scrambling of a modulated sequence by multiplication of a modulated sequence by a sequence of scrambling, and the second processor receives a scrambled sequence via each dedicated subcarrier, converts the received sequence into a signal of time domain and generates and transfers a preamble.
EFFECT: reduced ratio of peak power to average capacity of a preamble by means of scrambling.
