Abstract:This paper presents a novel phase precoding (preequalization) technique to equalize frequency-selective Rayleigh and Rician slowly fading channels for personal communication systems using phase modulation. In order to achieve intersymbol interference (ISI)-free transmission, the precoding technique predistorts the signal transmitted from a base station to a portable unit. The novelty of the technique lies in using a spiral curve design: 1) to ensure the stability of the precoder even in equalizing a non minimu… Show more
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.
