Abstract
This paper considers the improvement of CSI estimation accuracy in OFDM-based wireless packet transmission systems by exploiting the preamble signal as well as the pilot signal. The CSIs respectively estimated from the received preamble and pilot signal are combined according to the channel correlation between the preamble and the pilot signaling. The combining weight is analytically determined to minimize the mean squared error. Simulation results show that the proposed scheme is quite.
