DEVICE AND METHOD FOR GENERATION OF PREAMBLE SERIES IN COMMUNICATIONS SYSTEM WITH ORTHOGONAL MULTIPLEXING AND FREQUENCY SEPARATION OF CHANNELS

FIELD: engineering of devices for generating series of preamble with low ratio of pike to average power in communications system with orthogonal multiplexing and frequency separation of channels. ^ SUBSTANCE: in accordance to method, first series of preamble is generated, wherein odd data of input series of preamble are transformed to zero data, and even data of aforementioned series are transformed to nonzero data, first series of preamble is transmitted through one of two antennas, second preamble series is generated, wherein even data of input series of preamble are transformed to zero data, and odd data of aforementioned series are transformed to nonzero data, second series of preamble is transmitted through another antenna. ^ EFFECT: increased efficiency. ^ 6 cl, 10 dwg
