This paper addresses the channel estimation based on tentative data estimates in multicarrier systems, such as the LTE. We propose an iterative estimation approach based on solving in every iteration a specific weighted optimization problem. The weights are derived for two cases: known and partly known (or unknown) variances of the data estimation errors,(More)
This paper addresses the channel estimation in receivers of multicarrier communication signals, particularly in multiuser scenarios of the LTE uplink. B-splines are proposed for estimation of the time-frequency channel response. Cubic B-splines are considered as the appropriate basis functions allowing a trade-off between the estimation accuracy and(More)
