Abstract
Partial Transmit Sequence (PTS) is a promising scheme for improving peak-to-average power ratio (PAPR) performance of orthogonal frequency division multiplexing (OFDM), with no signal distortion. Unfortunately, a complicated phase weighting process is involved in the original PTS (O-PTS), which induces high complexity. In this paper, a selective weighting PTS (SW-PTS) PAPR reduction scheme is proposed. In SW-PTS, selective weighting is firstly employed for reducing computational complexity. Then, unlike O-PTS, some specialized phase weighting sequences are generated for weighting the first subblock sequence to improve PAPR reduction performance. With massive computer simulations being done, proposed SW-PTS can reduce computational complexity clearly and achieve similar PAPR reduction performance compared to O-PTS.
