Abstract(in English) In Impulse-Radio or DS/SS UWB communications, a prerake scheme has been proposed to achieve 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 comsumption in the terminal side. In this report, a precoded transmit path diversity scheme in an OFDM sysytem has been proposed. The proposed scheme makes use of the impulse response of the channel with the resolution of the FS interval and can achieve path diversity without oversampling the received signal on indoor channels.
