Abstract :
In this paper, we investigate an advanced peak windowing method as a peak-to-average power ratio (PAPR) reduction technique in orthogonal frequency division multiplexing (OFDM) systems. The advanced peak windowing method is performed by introducing new weighting coefficients in case that successive peaks are generated within a half of the window length. Applying the new weighting coefficients, we can tightly limit the successive peaks to the given threshold level. Through a computer simulation, we verify that the BER performance improvement can be achieved by the proposed peak windowing method while maintaining almost the same complementary cumulative distribution function (CCDF) and spectral characteristics.
