Abstract
OFDM (Orthogonal Frequency Division Multiplexing) technique has been widely adopted in many wireless communication systems due to its high data-rate transmission ability and robustness to the multipath fading channel. One major drawback of the OFDM signal is the high peak-to-average power ratio (PAPR) problem. The high PAPR results in the in-band distortion and out-of-band radiation when the OFDM signal is fed into a nonlinear power amplifier (PA).Large fluctuations of OFDM signal amplitude represents a major drawback for amplification in mobile communication systems. This paper enumerate an idea about comparison of PAPR reduction schemes in terms of its performance. Clipping at nyquist and oversampled rate, and Partial transmit sequence method of PAPR reduction are considered here for comparison in terms of Complementary Cumulative Distribution Function (CCDF) and Bit error rate.
