Özet
In this paper, it is recommended to combine the partial transmit sequence (PTS) and amplitude clipping (AC) methods as a solution to the peak to average power ratio (PAPR) problem of multi-carrier (MC) communication systems. The suggested technique is verified on zero tail discrete cosine transform spread OFDM (ZT-DCT-s OFDM), ZT discrete Fourier transform spread OFDM (ZT-DFT-s OFDM) and ZT discrete sine transform spread OFDM (ZT-DST-s OFDM) waveforms, from the next generation waveform alternative to OFDM, with classical OFDM waveform. Computer simulation studies are performed to verify the success of the recommended PTS-AC method over bit error rate (BER) and PAPR achievement benchmark. From the obtained results, it is observed that the suggested technique provides approximately 6 dB PAPR enhancement versus the original versions of the waveforms without compromising the BER performance. © 2021 IEEE.
