Abstract:A novel measurement-based antenna-height-dependent statistical root-mean-square (RMS) delay spread model under indoor stair environment is proposed. In this model, the RMS delay spread is described as a log-normal random variable with antennaheight-dependent parameters in both line-of-sight (LOS) and the non-LOS (NLOS) areas. The environmental independence of the RMS delay spread distribution is shown first. Then, the parameters of the proposed model are extracted using least-squares and maximum likelihood est… 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.
