FIELD: physics, communications.
SUBSTANCE: invention claims device and method of tone ranking for separation of signals from different base stations (BS) in high-rate packet data (HRPD) transfer systems, where packet data are received from higher level; received packet data are coded and modulated channel-wise; security tones are inserted into modulated packet data symbols; pilot signal tones are inserted using pilot signal tone location charter based on predefined pilot signal tone shifts; symbols of packet data processed by pilot signal tone location charter are expanded in spectre, so that BS for transmission of different broadcast programme content differ from each other; after reverse Fourier transform a cycle prefix (CP) is inserted over packet data symbols expanded in spectre, and symbols are transmitted.
EFFECT: insertion of pilot signal tones over equal intervals without overlaying direct current frequency with pilot signal tone, elimination of channel error assessment.
