Abstract:To utilize the spectrum efficiently, nine modulation and coding schemes had been specified in the EGPRS standard. This paper proposes a new closed-loop link adaptation by selecting the transmission mode according to the Rician channel k-factor. The proposed link adaptation incorporates only three identical modulated schemes due to the considerations of hardware complexity and implementation feasibility. Applying the proposed method to a real channel measured at urban Taipei city, the simulation results show th… 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.
