Abstract
Partial transmit sequence (PTS) scheme is one of the most effective way to reduce peak-to-average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) systems. The cyclic shift on time-domain PTS has better performance in PAPR reduction than that of the conventional PTS (C-PTS), and the receiver can recover phase rotations without using side information (SI). However, the receiver must know channel response before detecting and perform complex operations in order to detect the phase rotation factors. In this letter we proposed a pilot design method based on cyclic shift on time-domain PTS, which can estimate phase rotation factors and channel response more easily. Simulation results show that the PAPR performance of the proposed method is approximately same as the cyclic shift PTS scheme and the BER performance is also as well as C-PTS with perfect SI in multipath channel scene.
