— Orthogonal frequency division multiplexing (OFDM) is an attractive technique for wireless communication
applications. One of the challenging issues for OFDM is its high peak-to-average-power ratio (PAPR), which can lead
to low power efficiency and nonlinear distortion at the transmitter power amplifier. Clipping is a simplest technique for
PAPR reduction. We investigate, through extensive computer simulations, the effects of clipping and filtering on the
performance of OFDM, including the PAPR reduction capability, the peak regrowth effect and power spectral density. In
this paper the technique of Iterative clipping and filtering is simulated for OFDM and it is found that using this
technique with 4 iteration, PAPR is reduced to approximately 4 dB and effect of peak regrowth can be reduced
