FIELD: radio engineering, communication.
SUBSTANCE: method of creating an increased signature space describes the generation of a virtual signature using a combining operation over basic signatures. The generated virtual signatures are represented as base resource units (BRU) for transmission of the respective users. The combining operation is a line-by-line or column-by-column permutation for combining, in each of the virtual signatures, lines or columns of the corresponding basis signatures. Lines or columns represent sequences of frequency bands in one time interval or a sequence of assigned time intervals in one frequency range. Embodiments of the invention also comprise generating a plurality of the BRU block sets containing virtual signatures. Each of the BRU block sets is designed for the respective user.
EFFECT: increasing the space of low-density signatures for multiplexed transmissions for a plurality of users.
