Description: PEAK TO AVERAGE POWER RATIO REDUCTION OF DM
SIGNALS USING PEAK REDUCTION CARRIERS:
ABSTRACT
A technique is described for a better than 5 dB reduction
in the Peak to Average Power Ratio (PAPR) of an OFDM
signal. The optimal amplitude and phase of additional
peak reduction carriers (PRC) is obtained using a codebook,
which is obtained using a search of all possible
signal combinations.-PEAK TO AVERAGE POWER RATIO REDUCTION OF OFDM

Description: TR significantly reduces the PAPR when operating with an
optimal PRT set however, the performance of TR degrades with
nonoptimal PRT sets. Finding the optimal PRT set is a nondeterministic
polynomial-time (NP)-hard problem [4], which cannot
be solved. Therefore, one has to resort to suboptimal solutions
such as random set optimization-TR significantly reduces the PAPR when operating with an
