The orthogonal frequency division multiplexing (OFDM) is an attractive transmission technique for high bit-rate communication systems. OFDM has become a promising candidate for high performance 4G broadband wireless communications. One of the main disadvantages of OFDM is the high peak-to-average power ratio (PAPR) of the transmitter’s output signal. Selected-Mapping (SLM) with Genetic scheme which does not require the transmission of side information and can reduce the peak to average power ratio (PAPR) in turbo coded orthogonal frequency division multiplexing (OFDM) system is proposed. Simulation results show that the system can achieve significant reduction in PAPR and satisfactory bit error rate performance over AWGN channels.

Keywords : Orthogonal Frequency Division Multiplexing (OFDM), Selective Mapping (SLM), peak-to-averagepower-ratio (PAPR), Complementary Cumulative Distribution Function (CCDF), Bit Error Rate (BER).
