FIELD: communication equipment.
SUBSTANCE: invention can be used in wireless communication systems. For this, the precoding process is carried out with respect to the first baseband signal and the second baseband signal to generate a first precoding signal and a second precoding signal. Pilot signal is inserted into the first precoding signal and phase change is performed with respect to the second precoding signal. Pilot signal is inserted into second phase-modified precoding signal and phase change is additionally carried out with respect to the second phase-modified precoding signal with the inserted pilot signal.
EFFECT: technical result is increased transmission channel capacity.
