N2 - Partial transmit sequence (PTS) scheme is an attractive technique for peak-to-average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) systems. However it needs many candidates to obtain preferable PAPR performance, which will result in high computational complexity. In order to alleviate the problem, this paper proposes a novel partial transmit sequence (PTS) technique, in which real and imaginary parts of the candidate are separately multiplied with phase factors, moreover, PAPR is conjointly optimized in real part and imaginary part. In this scheme, the number of candidates is increased so that the PAPR performance is improved with less increase of complexity. Simulation results show that the PAPR performance of the proposed scheme is better than that of the conventional PTS scheme. Furthermore, compared with widely-linear selective mapping (SLM) scheme, the proposed scheme has the near PAPR performance and lower computational complexity for the same number of candidates.
