Abstract:Orthogonal time frequency space (OTFS) modulation technique is one-step more precoded system of the conventional orthogonal frequency division multiplexing (OFDM) system, i.e., a double precoded system. The OTFS system was suggested especially for the robust and reliable high-speed vehicle communications and massive multiple-input multiple-output (MIMO) systems. Nevertheless, this basic OTFS system has serious problems: high out-of-band (OOB) power emission and high peak-to-average power ratio (PAPR). This hig… 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.
