  Logarithmic Companding using Firefly Algorithm for PAPR Reduction in OFDM System

  By Kratika Mittal, Rekha Gupta

  Abstract: Orthogonal Frequency Division Multiplexing (OFDM) is a digital transmission method developed to meet the increasing demand for higher data rates in communications which can be used in both wired and wireless environments. However OFDM is handicapped with a major problem of high peak-to-average power ratio (PAPR), which gives rise to non-linear distortion, inter-symbol interference and out-of-band radiation. Several PAPR reduction techniques have been devised over the last few decades in …
