Abstract: In this paper, a hybrid technique using a low complexity selective mapping (LCSLM) cascading an improved μ law companding scheme (LCSLM- μ ) is proposed to reduce the peak-to-average power ratio (PAPR) and complexity in… read more here.

Abstract: The μ-law companding function has been applied widely in orthogonal frequency division multiplexing (OFDM) to reduce the peak-to-average power ratio (PAPR). However, nonlinear distortion caused by the μ-law companding function is considered a key impairment… read more here.
