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