Abstract

The invention relates to a transmission method and a radio system comprising at least one transmitter (200) and one receiver (100) which employ TDD duplexing when setting up a connection. The transmitter (200) receives signals propagated on different signal paths by means of antennas (201). The radio system comprises transmission means (220) which receive a signal from several polarization directions, measuring means (210) which measure signals received by the transmitter (200), said signals being combined into one signal on the basis of the measurement. The transmission means (220) polarize the signal and transmit the polarized signal to the receiver (100) in several polarization directions on the basis of the measurement performed by the measuring means (210).
