<p><strong>英文</strong></p><p><strong>A Simulation Study on Channel Estimation for MIMO-OFDM Based Beyond 3GMobile Systems</strong></p><p><strong>Abstract </strong>: 　Multi-Input Multi-Output antennas based Orthogonal Frequency-Division Multiplexing (MIMO-OFDM) has been chosen as the ai r interf ace technology f or Chinaps beyond 3G Time-Division Duplex ( TDD) mobile system in the FuTURE research project . Channel estimation plays a key role on the perf ormance of the MIMO-OFDM receiver. In this paper , we present f ive channel estimation algorithms and study thei r perf ormance in a simulated beyond 3G TDD mobile system. Simulation results show that the adaptive 2D-LMS algorithm we proposed recently has the best perf ormance when the signal to noise ratio is lower than 8 dB.</p><p><strong>Key words</strong> : 　OFDM; channel estimation ; mobile communication ; beyond 3G</p><br/>
