Abstract:Abstract-A cooperative MIMO system for range extension in sensor networks is considered. A local sensor group forms a consensus and seeks to transmit a common pool of data to a stand-off multi-element collector. Each sensor then transmits one column of an orthogonal space-time block code (OSTBC). The resulting increased effective power and diversity can yield substantial range increases for moderate numbers of sensors. The major problem is tracking the individual sensor frequency offsets, delays and sensor-to-… 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.
