Abstract :
We propose a simple adaptive algorithm for channel estimation of multiple antenna OFDM systems to provide competitive performance with low computational complexity and tracking ability. The derivation of the mean-squared error (MSE) for the proposed scheme is presented and the selection of the parameter in the scheme is analyzed by utilizing the derived MSE expression
