摘要：
In this paper, an adaptive path number selection mechanism is proposed to improve the accuracy of the frequency channel response obtained from the pilot-based channel estimation approach for QAM modulated MIMO-OFDM systems. The 2x2 space-frequency block code-dedicated short-range communication (2x2 SFBC-DSRC) system and a six-path channel model are considered as an example of the MIMO-OFDM system in the simulations. Simulation results prove the relevant benefits of the proposed suboptimum channel estimation approach used in time-varying fast fading channels.
