| Research Abstract |
This research proposes to employ frequency-domain oversampling together with advanced signal processing techniques to deal with multicarrier systems (OFDM, MIMO-OFDM, MC-CDMA, etc.) in general. It is shown that frequency-domain oversampling based approach enables efficient exploitation of frequency diversity to improve system performance under various conditions such as multiple antennas, doubly-selective fading, multi-user interference, etc. In addition, the proposed approach also leads to some novel blind channel estimation schemes for generic multicarrier systems.
