A companding technique using the hyperbolic tangent transform is proposed for reducing the peak-to-average-power ratio (PAPR) of orthogonal frequency division multiplexing (OFDM) signals. This technique is practical and can be implemented easily in analog integrated circuit design. The PAPR value of an OFDM system and the optimal companding coefficient to(More)
