Hybrid-Domain Evaluation PTS with Adaptive Selection Methods for PAPR Reduction

Abstract: The partial transmit sequence (PTS) technique is a fairly suitable scheme to mitigate the high peak-to-average power ratio (PAPR) problem inherent in 5G multicarrier systems, especially considering a high-order QAM modulation design. However, the high computational complexity level and the speed of the convergence for optimizing the phases of the transmitting signal restrict this technique in practical applications. In this paper, a low-complexity frequency-domain-evaluated PTS (F-PTS) based on a spacing multi… Show more

“…Nowadays, many researchers have proposed various well-known technologies to reduce PAPR in OFDM systems [ 11 , 12 , 13 ], such as clipping, SLM, PTS, TI, TR, etc. Among them, the clipping technique [ 14 , 15 ] is the easiest to implement, because only the input signal needs to be limited, but the clipped signal is prone to nonlinear distortion, and the location and size of the clipping are difficult to decide and store, which results in BER performance degradation [ 16 ] and spectral efficiency decline.…”
