摘要：
In this paper, we propose a semi-blind MAP (maximum "a posteriori") channel estimation method based on an Expectation-Maximization Block algorithm (EM-MAP-Block). In the OFDM communication context, our algorithm still have a linear arithmetical complexity. However, it yields to an SNR improvement going up to 3.5 dB compared to classical training sequences based channel estimation method in the context of 5 GHz OFDM WLANs. The new algorithm performs better than already existing recursive algorithms and block algorithms.
