In mobile communications, MIMO-OFDM system performance suffers severe degradation caused by the large delay spread channel greater than Guard Interval (GI). This is because the excess delay results in considerable Inter-Symbol-Interference (ISI) between adjacent symbols and Inter-Carrier-Interference (ICI) among subcarrier in the same symbol. In the case of Scattered Pilot, the interference of pilot signals causes the deterioration of channel estimation. We propose the interference lump-sum compensation scheme using the parallel replica signals. We make parallel replica signals from received signals and channel responses. We subtract the replica signals from the received signals to compensate ISI and ICI. After compensation, we calculate the channel estimation again and obtain the updated CSI. Finally, we operate an equalization using the updated CSI and detect the received signals which are compensated the interference. |
