Abstract:In this paper, we study DFT-bank transceivers with filter length longer than the block size. We show how to optimize the DFT-bank transceiver so that both the intra-band and cross-band interferences are minimized for unknown multipath channels. No costly post processing technique is needed and the only channel dependent part is a set of one-tap equalizers at the receiver. The optimization problem is formulated as a Rayleigh-Ritz ratio whose solution is well-known. Experiments are carried out for transmission o… 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.
