Abstract
A method for reducing the peak-to-average power ratio (PAPR) in an OFDM based wireless system is disclosed herein. The reduced PAPR may be achieved by appropriately selecting subpackets for transmission. For example, a scheduler may elect to sequentially transmit the subpackets in an order related to the PAPR of each of the subpackets until at least one of the subpackets is properly received. In one embodiment of the instant invention the order of transmission is selected to be from lowest to highest PAPR.
