OFDM Peak-to-Average Power Reduction Scheme With Spectral Masking

Overview Clipping and filtering can be a simple and effective method of reducing the peak-to-average power ratio (PAPR) for an orthogonal frequency division multiplexed (OFDM) signal. To be effective the clipping must be performed on an oversampled version of the time domain signal, but this results in out-of-band (OOB) power. In this paper it is shown that if the OOB power is limited rather than completely eliminated much less peak regrowth occurs. Simulation results are presented for HIPERLAN2.
