Abstract:SUMMARYThe CDMA system using DS/SS/GMSK modulation can realize a high spectral efficiency by using the constantenvelope property of GMSK modulation, even if the signal is band-limited and the transmitter is nonlinear. This paper discusses the optimization of a receiver in order to further improve spectral efficiency. The idea is to apply optimal weights to the despreading matrix. Using the signal-tonoise power ratio based on a linear approximation to the DS/SS/GMSK waveform, the weights that minimize the signa… 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.
