| Abstract(in English) | OFDM (Orthogonal Frequency Division Multiplexing) is robust to frequency selective fading due to multipath propagation. However it is vulnerable to time-variation of the channel caused by Doppler spread. We have already proposed a Doppler spread compensator based on space-domain interpolator. In this paper, we show the result of an experiment demonstrating the effect of the scheme. Furthermore, we propose a new compensator, which is capable of compensating not only for Doppler spread but also for deep fading by making effective use of pre-DFT combining space diversity scheme. Computer simulation result shows the proposed pre-DFT combining diversity with space-domain interpolator is an efficient technique to the bit error rate degradation due to multipath fading and Doppler spread. |
