Orthogonal Frequency Division Multiplexing (OFDM) has become the popular modulation technique in high speed wireless communications. It is more advantageous over other technologies.But despite its advantages it has some obstacles also. The high peak-to- average ratio is the main obstacle which causes non-linearity at the receiving end. In this paper we discuss about the PAPR in the OFDM system ,its effect and name some techniques which can be used to reduce the PAPR according to the requirement…
