    Abstract

    In impulse-radio or DS/SS UWB communications, a prerake scheme has been proposed to achieve path diversity while reducing computational complexity in a mobile terminal. On the other hand, in an OFDM system, fractional sampling (FS) has been proposed to achieve path diversity with a single antenna. However, in the FS-OFDM system, it is necessary to oversample a received signal that leads to larger power consumption in the terminal side. In this paper, a precoded transmit path diversity scheme in an OFDM system has been proposed. The proposed scheme can achieve path diversity without oversampling the received signal.
