Abstract
A simplified Doppler diversity technique for orthogonal frequency division multiplexing (OFDM) high-speed mobile communication systems has been proposed in this paper. And SIR has been analyzed for OFDM receiver with the proposed Doppler diversity without losing the diversity performance. The optimal configuration of this receiver has also been researched to improve the system performance. Finally, simulation results of SIR for OFDM receiver and comparison have been given.
