Abstract:As a building block toward a simple and scalable solution for massive random access, we introduce collisionresolution algorithms using successive interference cancellation (SIC) based on the received signals, with no need for any coordination or codebook differentiation. We first consider twouser multiple access with the ZigZag algorithm. We prove that the original ZigZag and a modified version of it, called double-zipper ZigZag, attain the same performance as the optimal coordinated time-sharing in the high s… 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.
