FIELD: physics, communication.
SUBSTANCE: invention concerns communication technics. Various types of pilots-signals include - the pilot-signal of a beacon, pilot-signal MIMO, a controllable basic signal or the controllable pilot-signal, and the pilot-signal bearing. For this purpose the pilot-signal of a beacon transmit through all transmitting antennas, and it can be used for timing or frequency entrapment. Pilot-signal MIMO is transmitted through all transmitting antennas, but it is coated with the various orthogonal codes, appointed to transmitting antennas. Pilot-signal MIMO can be used for a channel estimate. A controllable basic signal is transmitted in certain natural modes of channel MIMO, and it is specific to the user terminal. The controllable basic signal can be used for a channel estimate. The pilot-signal of the bearing can be transmitted through the determined sub-ranges of the antenna and can be used for tracing of a phase of a signal of the bearing. Various plans of transmission of a pilot-signal can be developed, being grounded on various combinations of the specified various types of pilots-signals.
EFFECT: formation of the pilots-signals approaching for use in systems MIMO, and providing support of various functions.
