Channel estimation with transmitter diversity for high rate WPAN systems
Dong-Jun Cho, Young‐Hwan You, Hyoung‐Kyu Song · IEICE Transactions on Communications · 2004
This letter presents an investigation of channel estimation scheme for a high rate WPAN system using multiple transmit antennas over indoor wireless channel. A simple algorithm utilizing the autocorrelation property of a CAZAC preamble is proposed for channel estimation. Simulation and analytical results show the performance of the proposed algorithm in terms of mean square error (MSE) of channel estimation. At the same time, the effect of imperfect channel estimation introduced by relatively large RMS delay spread is highlighted.
