The resulting algorithm is a space alternating generalized expectation-maximization (SAGE) algorithm which updates the data sequences serially and the channel parameters in parallel, leading to a receiver structure that also incorparates interchannel interference cancellation. Its performance is compared with various Minimum Mean Square Error (MMSE) estimators for a multipath frequency selective fading channel using simulations. It is illustrated that the proposed SAGE algorithm performs better than the MMSE estimators considered in this paper.eninfo:eu-repo/semantics/closedAccessSuboptimal receiverjoint channel estimation and data detectiondownlinkMC-CDMASAGE algorithmArticle138312Q1138115WOS:000298299600039Q2
