Abstract
This article proposes a novel wireless channel estimation method suited for fast fading environment. Generally, forward error correction (FEC) requires long block code length to raise error correction capability while it deteriorates the channel tracking accuracy in pilot-aided estimation. To meet these trade-off demands, we propose a frame splitting and decision directed channel estimation (DDCE). It splits information data in half and estimate channel state information (CSI) of the former part. That of latter is simply extrapolated using the former CSI. Computer simulation result shows that the proposed method can improve bit error rate performance even at fast fading environment.
