FIELD: communications.
SUBSTANCE: user data are sent in parallel with information of the transmitter in many implementation versions In many cases the user data is allocated more than 20% of the maximum output power of the transmitter. A defined power value of tones is used. The tones are used for transmitting information from the transmitter, with simultaneous transmission of user data using more than 20% of the available transmission power.
EFFECT: increased efficiency.
