FIELD: information technology.
SUBSTANCE: disclosed is a wireless data transmission system having a plurality of antenna pairs; a functional demodulation module; and a transmission characteristic correction module. Each of the plurality of antenna pairs includes a transmitting antenna and a receiving antenna. A wireless signal transmitted from the transmitting antenna directly reaches the receiving antenna as a wanted wave. Meanwhile, a wireless signal transmitted from another transmitting antenna reaches that receiving antenna directly as an unwanted wave. The functional demodulation module, which corresponds to each antenna pair, demodulates the modulation signal received by the receiving antenna. The transmission characteristic correction module calculates correction based on the transmission characteristic for the transmission space between the transmitting and receiving antennae based on demodulation signals demodulated by the functional demodulation modules, so as to obtain an output signal corresponding to the transmission object signal.
EFFECT: possibility of using MIMO technology without OFDM modulation.
