This paper presents a new block iterative/adaptive frequency-domain channel estimation scheme, in which a Channel Frequency Response (CFR) is estimated iteratively by the proposed Weighted Element-wise Block adaptive frequency-domain Channel Estimation (WEB-CE) scheme using the soft information obtained by a Soft-Input Soft-Output (SISO) decoder. In the WEBCE, an equalizer coefficient is calculated by minimizing a weighted conditional squared-norm of the a posteriori error vector with respect to its correction term. Simulation results verify the superiority of the WEB-CE in a time-varying Typical Urban (TU) channel.
