Abstract :
A novel transform technique is proposed for reducing the peak-to-average ratio (PAPR) of an orthogonal frequency division multiplexing (OFDM) signal. Large OFDM signals are replaced by small complementary signals according to the proposed method. It has a low SNR loss in bit error rate while achieving a significant reduction of PAPR. It is shown by computer simulations that the proposed method can outperform the well-known clipping filtering scheme and μ-law companding technique substantially.
