    A precoded transmit path diversity in OFDM has been proposed to shift the signal processing burdens for fractional sampling (FS) from a receiver to a transmitter. It achieves path diversity without oversampling the received signal at the receiver side on time invariant channels. However, it does not take time variant channels into consideration. On time variant channels, inter-carrier interference (ICI) deteriorates the BER performance. In this paper, the precoding for both ICI suppression and path diversity combining at the transmitter side has been proposed. It can achieve ICI suppression and path diversity without any specific signal processing at the receiver.
