Abstract

Orthogonal Frequency Division Multiplexing (OFDM) is an efficient modulation technique for high data rate communication systems. Peak to Average Power Ratio (PAPR) is one of majors problems in OFDM system. In this paper, a joint clipping and square rooting (SQRT) method has been suggested and investigated for PAPR reduction of OFDM signal. The SQRT process changes the statistical characteristics of the OFDM signal from Rayleigh distribution to Gaussian like distribution after the clipping process. This change in statistical distribution results changes of both the peak and average power values of OFDM signals, and consequently reduces significantly the PAPR value. This technique decreases the bit error rate (BER) slightly while significantly reduces the PAPR value. For 64-QAM OFDM system with 1024 subcarriers, up to 7 dB PAPR reductions with fixed degradation in bit error rate (BER) equal to 2.5 dB can be achieved by combining both clipping and square rooting scheme.

Distortion-compensation scheme for PAPR reduction of OFDM signals
WiCOM'09: Proceedings of the 5th International Conference on Wireless communications, networking and mobile computing

A distortion-compensation scheme is proposed for the PAPR reduction of orthogonal frequency division multiplexing (OFDM) signal. In the transmitter, clipping the peak envelope of the input signal to a predetermined value will cause in-band distortion. ...
