As we know in today world communication is increasing exponentially. We want the best quality of service at economical cost and at high speed. When we look in deep how these parameters can be carried out then lots of problems arises in front of us and one of them is PAPR. There are various technique to reduce like tone injection, OFDM is a multi-carrier transmission scheme. This is used in 4th generation wireless communication. The main advantage of OFDM, cross talk between the sub-channels is eliminated and intercarrier bands are not required. Coin have two sides similarly OFDM have some advantages and disadvantages, according to this quotation there has a major drawback arises in the OFDM is known as a PAPR (Peak to average power ratio). PAPR reduction techniques, based on computational complexity, bandwidth expansion, spectral spillage, and performance. PAPR problem is reduced by the technique.
