Abstract
According to one embodiment of the present invention, a method is provided in which a set of data symbols is partitioned into a plurality of subsets. The data symbols are used to modulate the sub-carriers that transmit data signals from a transmitter to a receiver. The subsets of the data symbols are assigned to the corresponding sub-carriers based on a predefined set of assignments. The assignment which results in the minimum PAPR is then chosen. The information identifying which assignment is used is communicated to the receiver which then uses this information to place the data symbols back to their true positions.
