Selected mapping is an accurate method for reducing peak to average power ratio from orthogonal frequency division multiplexing. A fundamental weakness of selected mapping is the high computational complexity. To reduce the complexity of the selected mapping, the real and imaginary part of the orthogonal frequency division multiplexing signals is treated separately. Numerical sequences and even real and imaginary elements are obtained using Fourier transform properties. More candidates are produced with a different combination of all the following sequences. The proposed scheme produces less computational complexity using the IFFT algorithm for M4 equations only. The simulation results show that the proposed design reduces the good performance of peak to average power ratio and also reduces computational complexity compared with the selected mapping design.EnglishOrthogonal Frequency Division Multiplexing; Conventional Selected Mapping; Fast Fourier TransformArticle
