We analyze and optimize the performance of a trellis-coded modulation system where receive antenna diversity is implemented. The adaptive coded modulation scheme alone is a promising tool to combat fading and it improves the spectral efficiency in mobile communications. The improvement can be even higher when we have multiple receiver antennas. The analysis is done in the presence of both estimation and prediction errors. Independent Rayleigh fading on each subchannel is considered, and maximum ratio combining is employed on the receiver side. As expected, the average spectral efficiency increases, while bit error rate is always fulfilled.
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.
