In this paper, we propose a modified selected mapping technique to reduce the peak-to-average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) system. In this technique, we choose a vector with low PAPR in each coset of a linear block codes as its coset leader, instead of the weight vector in conventional technique. And a sequence which is most likely to yield the lowest PAPR is chosen to transmit before IFFT by a decision algorithm. Simulation results show that the… CONTINUE READING
