ABSTRACT:
When carrying out a channel compensation of a data symbol, a channel estimation value of the reference symbol of the frame itself and that of a reference symbol of the preceding frame are used. In this event, if an AGC gain at the time of a channel estimation value by a reference symbol of the frame itself is different from that of a frame of the reference symbol of the preceding frame, and if an AGC gain of the reference symbol of the frame itself is the same as that of a data symbol to be subjected to a transmission compensation, then the channel estimation value by the reference symbol of the preceding frame is corrected so as to cancel the difference of the AGC gains, followed by using it for a channel compensation of the data symbol.
