Abstract

Orthogonal frequency division multiplexing (OFDM) is a robust and effective multicarrier transmission technique for high speed communication in wireless mobile environment and applications. A major challenging issue in application of OFDM is its high peak to average power ratio (PAPR). Partial transmit sequence (PTS) scheme is an attractive technique for PAPR reduction in OFDM systems. In conventional PTS, an exhaustive search for phase sequences is needed to obtain desirable PAPR performance, which results in high computational complexity. In this paper, a hybrid combination of tree PTS (T-PTS) algorithm and real part-imaginary part (RP-IP) separation technique is proposed. The simulation results of the proposed technique show improved PAPR performance with remarkably reduced bit error rate (BER), over all variants of PTS. Also, the technique offers significant reduction in computational complexity over conventional PTS technique.
