Summary:
In general, if the maximum delay spread is longer than guard interval (GI), the system performance is significantly degraded. The conventional time-frequency interferometry (TFI) for OFDM does not consider with time-variant large delay spread channel. In this paper, we propose a novel time domain inter-symbol-interference (ISI) cancellation scheme with replica signal based inter-carrier-interference (ICI) compensation for TFI-OFDM.
