FIELD: radio engineering, communication.
SUBSTANCE: invention relates to communication. The method includes steps of constructing a long training field (LTF) sequence of a preamble by combining a plurality of interpolating sequences with LTF tone values associated with at least one of the IEEE 802.11n standard or the IEEE 802.11a standard, wherein the LTF tone values cover at least a portion of bandwidth of a first size, and each of the LTF tone values is repeated one or more times for different subcarriers; rotating phases of tones of the LTF sequence per bandwidth of the first size in order to reduce a peak-to-average power ratio (PAPR) during transmission of the LTF sequence; and replacing tones of the LTF sequence at pilot locations with a defined stream of values chosen in order to reduce the PAPR.
EFFECT: constructing a training sequence as a part of transmission preamble in order to minimise (or at least reduce) a peak-to-average power ratio (PAPR) at a transmitting node.
