Orthogonal Frequency Division Multiplexing (OFDM) has been currently under intense research for wireless transmission due to its robustness against multipath fading. However, it has some limitations such as the Peak-to-average power ratio (PAPR), which restricts its use. It reduces the efficiency of the system. The aim of this paper is to analyze the various PAPR reduction techniques.
