A simple nonlinear companding transform which makes full use of the statistical characteristics of the original multi-carrier signals and combining them with the simplest clipping theory is proposed to reduce the peak-to-average power ratio (PAPR) of multi-carrier systems. By making a simple truncation to the Rayleigh-distributed original signals, the proposed scheme not only has low implementation complexity but also outperforms conventional companding schemes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
