摘要：

In this letter, partial transmit sequences (PTS) based on parallel tabu search (Parallel TS-PTS) scheme is proposed to reduce the peak-to-average power ratio (PAPR) of orthogonal frequency division multiplexing (OFDM) signals. PTS is a distortionless PAPR reduction technique, but its high search complexity for finding optimal phase factors must be reduced for usable applications. Parallel TS-PTS is compared to different PTS schemes for PAPR reduction and search complexity performances. The simulation results show that the proposed parallel TS-PTS method provides good PAPR reduction and bit-error-rate (BER) performances.
