ABSTRACT:
The invention relates to a radio system and a data mission method. In the method of the invention, a transmitter codes a signal to be transmitted such that at least two non-orthogonal channels are obtained; the transmitter transmits the coded channels via at least two different transmit antenna paths; and a receiver receives the signal. The transmit antenna paths are divided into at least two different groups; and the signals to be transmitted through the different groups are weighted in the transmitter by means of changeable weighting coefficients determined for each group.
