Tone Reservation as a PAPR reduction technique

PAPR (peak to average power ratio) is a major problem that faces all OFDM systems.

Description

if we have 16 subcarriers let us dedicate r1,r2,r3 and r4 as PRC or peak reduction carriers and transmit on x1:x12 so when x1:x12 summation creates a peak, a combination from r1,r2,r3 and r4 creates an anti peak but not the exact anti peak or the output would be a flat signal from which data can not be retrieved.
