Abstract

In an apparatus for generating a transmit sequence comprising information from a plurality of information channels, a first means serves for generating a plurality of different candidate channel sequences from information of a first information channel of the plurality of information channels using a first code sequence associated with the first information channel, wherein each candidate channel sequence carries the same information as the information of the first information channel. A second means is provided to provide at least one candidate channel sequence for a second information channel from the plurality of information channels using a second code sequence associated with the second information channel and differing from the first code sequence. To receive an optimum transmit sequence resulting in a minimum out-of-band radiation combined sequences are examined, wherein each combined sequence may be obtained by a combination of at least one candidate channel sequence from each information channel. After this either the combined sequence is selected resulting in a minimum out-of-band radiation or the optimum candidate channel sequences are selected from the individual information channels, which together result in the optimum combined sequence causing a minimum out-of-band radiation. Therefore it is possible to reduce peak values e.g. occurring in the code multiplex modulation concept in the transmit sequence distortion-free.
