  Peak to Average Power Ratio (PAPR) of Orthogonal Frequency Division
Multiplexing (OFDM) is a long-standing problem which has been hindering its
performance for decades. In this paper, we propose a new PAPR reduction scheme
based on shifting pilot locations among the data symbols. Since no side
information is sent to the receiver about the pilot locations, a novel pilot
detection algorithm is devised here exploiting the pilot power and the relative
constant distance property of pilots. The proposed scheme attains around 1.5 dB
PAPR reduction. The pilot detection accuracy is shown to be very excellent
ranging from 80% to 99% at 0 dB of Signal to Noise Ratio (SNR) in different
parameters. This scheme is very spectrally efficient with reduced complexity
without degrading BER performance significantly
