In recent past years, PAPR (Peak-to-Average Power Ratio) of OFDM (Orthogonal FrequencyDivision Multiplexing) system has been intensively investigated. Published works mainly focus on how to reduce PAPR. Since high PAPR will lead to clipping of the si

One of the main disadvantages of Orthogonal Frequency Division Multiplexing (OFDM) is its high Peak-to-Average Power Ratio (PAPR), which significantly reduces the efficiency of the High Power Amplifier (HPA). Due to the simplest way for PAPR reductio

High Peak to Average Power Ratio (PAPR) is a main area of concern in multi-carrier communications as in Orthogonal Frequency Division Multiplexing (OFDM) modulated transmission. Several techniques have been devised to reduce the PAPR of the OFDM sign

Peak-to-Average Power Ratio (PAPR) reduction techniques based on nonlinear functions (clipping, companding techniques, etc) are the most straightforward PAPR reduction methods. These techniques reduce the PAPR at the cost of generating distortions. I

One of the major drawbacks of Orthogonal Frequency-Division Multiplexing (OFDM) is the large envelope fluctuations which either require an inefficient use of High Power Amplifiers (HPA) or decrease the system performance. Peak to-Average Power Ratio
