Abstract
The invention relates to a transmission method and a radio system comprising a transmitter and a receiver that communicate with each other by means of signals they have transmitted. The signals propagate along different paths from the transmitter to the receiver, which comprises means for combining the signals that have propagated along different paths after the reception. The radio system comprises transmitting means for transmitting for each connection at least two signals that are combined in the means into one signal, and measuring means for measuring the combined signal and for estimating the optimality of the transmission. The radio system also comprises control means that adjust, on the basis of the measurement and estimation, the phase of at least the signal that is to be transmitted in the downlink direction in the signal transmission by the transmitting means in order to decrease accumulation of signals during the combining of the signals.
