Logarithmic Companding Technique to Improve Performance of SC-FDMA Systems

Indian Journal of Science and Technology, 2016
Objectives: This paper proposes logarithmic companding technique to improve PAPR and BER performance of conventional Single Carrier Frequency Division Multiple Access (SC-FDMA) system. Methods/Analysis: The lower signal envelope fluctuations in SC-FDMA signal results in low peak to average power ratio, in contrast to that of OFDMA.

A Companding Technique to Reduce Peak-to-Average Ratio in Discrete Multitone Wireline Receivers

IEEE Open Journal of Circuits and Systems
Multicarrier modulation, while providing a theoretical pathway to data rates approaching the Shannon limit and being extensively utilized in wireless communication, has encountered limited application in high-speed wireline communication. This limitation is primarily due to substantial large amplitude peaks, which necessitates a reduction in the signal&
