Abstract

Apparatus configured to receive a first signal comprising at least one frequency domain value; map the first signal to a second signal comprising at least two clusters, each cluster comprising a whole number multiple of a first number of sub-car-rier 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 val-ues is mapped to a sub-carrier value of the one of the at least two clusters dependent on a cluster selection.
