| Abstract: | In this paper, a channel estimation and multiuser detection method is presented for uplink MC-CDMA systems in time-varying environment. Based on the fact that the channel coefficients of two successive symbols are highly correlated, joint channel tracking and signal detection are carried out iteratively. A major contribution of the proposed approach is that it enables robust error propagation control, and is capable of detecting and tracking abrupt channel changes effectively. Simulation examples demonstrate the robustness of the proposed algorithms. | ||
