Optimized Companding Technique using Firefly Algorithm for PAPR Reduction in OFDM System
Abstract: AbstractThe current trends in wireless industry are based on multi-carrier transmission technique such as Orthogonal Frequency Division Multiplexing (OFDM) which provides high data rates and is highly immune to frequency selective fading. 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 …
