PAPR Reduction using Tone Reservation Method in OFDM Signal

In this paper, we are going to propose ‘Tone Reservation' technique to reduce PAPR (Peak to Average Power Ratio) in OFDM signal using new algorithm. It is less complex and also calculates its own threshold value at the time of communication. It also calculates its PRT signal while other algorithms requiring predetermined threshold and PRT. It modifies the data by ‘bit by bit' comparison with a modified copy of itself (algorithm modified) thus scaling the peaks as and providing a decent BER and good PAPR reduction.
