This paper presents a robust block iterative/adaptive frequency-domain channel estimation scheme, in which a channel frequency response (CFR) is estimated iteratively through the proposed weighted element-wise block adaptive frequency-domain channel estimation (WEB-CE) using the soft information obtained from a soft-input soft-output (SISO) decoder. In the WEB-CE, an one-tap equalizer first structures...
In the space-time block-coded (STBC) single-carrier systems with a cyclic-prefix, decoupling and equalization procedures at the receiver require an exact channel impulse response (CIR). In this paper, we propose a weighted STBC-like matrix-wise block adaptive/iterative frequency-domain channel estimation (WSB-CE) that is operated iteratively by using soft information obtained from the SISO decoder...
