| Abstract(in English) | Currently, Multi-band OFDM (MB-OFDM) is considered as one of the modulation schemes of UWB and is actively investigated. On the other hand, diversity technology has been actively investigated. Single-Input Multiple-output (SIMO) is an antenna technology in which multiple antennas are used for diversity at the receiver. However MB-OFDM is expected to used as wireless USB. It should be implemented in small electronic devices like PDA, digital camera and cellular phone. It is very difficult to keep multiple antennas apart on such small devices in order for antennas to receive uncorrelated signals. In this paper, we propose a single antenna scheme that achieves diversity like SIMO. This scheme is called Fractional Sampling (FS). When FS is used, A/D conversion speed needs to be increased. Therefore, we consider the tradeoff between the resolution and the sampling rate of the A/D converter. As a result, FS can improve the BER performance only with one antenna. |
