Partial transmit sequence (PTS) scheme is one of the distortionless PAPR reduction scheme in multicarrier systems. The conventional PTS scheme exploits the frequency-domain phase rotation to generate low PAPR candidate signal, however it suffers from both high complexity and side information (SI). This paper proposes a time-domain PTS scheme without SI for single carrier frequency division multiple...
Signal to clipping noise ratio (SCR) and active-set methods are two existing peak to average power ratio (PAPR) reduction methods based on tone reservation. In this paper, we compare the PAPR reduction performance of these two methods, and the computational complexity is analyzed. The simulation results show that active-set method requires less computational complexity than that of SCR method while...
Partial transmit sequences (PTS) is a class of distortless PAPR reduction techniques for OFDM systems. However, the high complexity of PTS remains a problem. In the work by Baxley and Zhou (2007), the authors show that the PAPR reduction performance of PTS is not as good as that of another distortless technique-selected mapping (SLM) with the same computational complexity. To alleviate this problem,...
High peak to average power ratio (PAPR) is one of the main disadvantages of OFDM. Clipping can reduce the PAPR but suffers from high out-of-band distortion. Recently, peak cancellation is introduced to reduce the out-of-band radiation with a band-limited cancellation function. In this paper, a set of windowing function is applied as the cancellation function. Furthermore, the cancellation function...
