A Novel Approach to Deducing of the Data- PAPR Relation for OFDM System


Orthogonal Frequency Division Multiplexing (OFDM) is a very attractive technique for high-data-rate transmission in wireless and wired applications. The main drawback of the OFDM technique is its high peak to average power ratio (PAPR). Several approaches exist to reduce PAPR of OFDM symbols. All the previous approaches have a common disadvantages that are not having a scientific or mathematics rules to prove them or to measure the effect of these methods on PAPR. This paper will propose a useful model for the relation between the input data and output PAPR as main aim. This aim satisfies in two steps: 1- Study and analyze the effect of peak value (PV) problem in OFDM system, that intern influence directly in the value of PAPR. 2- Conclude the results in a graphical model to joint the relation between the input data and output PAPR.
