SYSTEM AND METHOD OF IMPROVING POWER EFFICIENCY IN WIRELESS COMMUNICATION SYSTEM

摘要

An apparatus may comprise a signal mapper to map a pre-emphasized signal to sub-carriers symmetrically about DC, and a peak-to-average-power reduction (PAPR) module arranged to receive a pre-emphasized signal and treat the pre-emphasized signal so as to reduce PAPR in a transmit signal sent from the transmitter. Other embodiments are described and claimed.
