Abstract

Channel state information (CSI) is often required for efficient digital wireless communication. We discuss channel state estimation in the CDMA multiuser detection problem. An iterative scheme for joint channel state estimation and multiuser detection is discussed. For channel state estimation two heuristic methods are formulated. Their dynamical behaviors are studied analytically and numerically.
