An apparatus may include a transmitter including a peak-to-average-ratio-reduction transformer to transform fine constellation data components (238) whereas coarse constellation date (239) are not transformed.
At the receiver, the fine components are inverse transformed and recombined with the received coarse component to regenerate the signal.
A possible transformation lowering the PAPR of the fine components is the Hadamard transform.
The components at the transmitter can be combined in a MIMO transmission.
