This paper considers the use of digital clipping techniques for OFDM transmission, so as to reduce the envelope fluctuation of the transmitted signals. The impact of oversampling and filtering issues is taken into account, together with the type of clipping and the choice of the clipping level, when calculating power spectral densities and BER performances. Our results show that an appropriate envelope clipping, together with a small oversampling factor and a mild filtering, leads to the best performance and is strongly recommendable for OFDM applications
