Abstract
This paper investigates a new time domain channel estimation for MIMO OFDMA downlink systems. Compared to classical frequency domain channel estimation, time approach allows improvements in a multi-antenna system. Nevertheless, the presence of null carriers in the spectrum leads to performance degradation because of ”border effect” phenomenon. An improved time domain channel estimation for MIMO-OFDMA system is proposed for downlink transmission and compared to classical channel estimation methods. Besides, this channel estimation process can be applied in any SISO and/or MIMO multicarrier transmission.
