Abstract
In orthogonal frequency division multiplexing (OFDM) system, high peak-to-average power ratio (PAPR) is the main drawback. In this paper, a Weighted Mean scheme is proposed to reduce the high peakto- average power ratio of the discrete OFDM signal without difficulty in removing the mean weight at the receiver section. In the proposed scheme, Weighted Mean scheme is imposed on every two successive positive and negative discrete OFDM signal point at the transmitter section and original discrete OFDM signal is completely regained without distortion in removing the Weighted Mean at the receiver section. The simulation result shows that bit-error-rate (BER) performance of the Weighted Mean scheme is enhanced compared to both weighted and clipping technique.
