Abstract(in English) | When carrying out mobile reception of the OFDM signal, the performance of the receiver is much degraded by the Doppler shift phenomenon because the frequency difference between the adjacent sub-carriers in OFDM is small. Since the omni-antenna Then, in this paper, we propose a Doppler shift compernsation system using an antenna with non-uniform sectors to receiver the signal through multi-path antenna. The received signal at a mobile antenna has a wide Doppler frequency shift range. The sector antenna divides the whore range into several narrow ones. The non-uniform sectors of the antenna can make these range equal. The compensation system easily combines these equal ranges. Computer simulations show that our proposed system has better performance than a uniform sector antenna compensation system. |
