Apparatus configured to receive a first signal including at least one frequency domain value; map the first signal to a second signal including at least two clusters, each cluster including a whole number multiple of a first number of sub-carrier values, wherein each first signal value is mapped to one of the at least two clusters and each of the at least one first signal values is mapped to a sub-carrier value of the one of the at least two clusters dependent on a cluster selection. |
