A method transmits data bits between at least one subscriber station and a transmitter in a radio communication system. Each data bit is transmitted on at least two different units of a first radio resource. On the emitter side, the data bits are spread for each unit of the first radio resource in such a way that each data bit is multiplied by a code matrix of the same matrix code group for the first radio resource units whose lines display respectively a spreading code realigning to a second radio resource and the columns display respectively a spreading code relating to a third radio resource.
