摘要：At a first equalizer A, a scattered pilot signal is interpolated in time directionand frequency direction, thereby obtaining a channel characteristic H. By complex-dividinga received signal Y subjected to FFT by the channel characteristic, the respective signal isreconstituted. At a second equalizer B, a resultant signal is hard-decided, therebyobtaining a mapping vector X. Then, by dividing the received signal Y by X, a channelcharacteristic is calculated again. The calculated channel characteristic having reliability issubstituted for the original channel characteristic. The substituted channel characteristicis filtered in frequency direction. In this way, a channel characteristic H' is calculated againand a signal point is reconstituted.
