Abstract :
This Orthogonal Frequency Division Multiplexing (OFDM) is an efficient multiplexing & a bandwidth efficient modulation scheme in wireless communications.However, OFDM faces the high Peak-to Average Power Ratio (PAPR) problem that is a major drawback of this multicarrier system which leads to power inefficiency in the RF section of the transmitter.Thus, the OFDM signals with high PAPR could seriously be distorted by the non-linearity of the HPA, resulting in degradation of both spectral efficiency (SE) and energy efficiency (EE) performances. Our paper will review a few techniques to reduce the high PAPR to combat multipath fading and signal distortion which will facilitate better data transmission.
