<P>PROBLEM TO BE SOLVED: To provide a DC-component removing function because a DC offset tends to change in accordance with time lapse due to an AGC effect, the offset occurs in either or both of an I and a Q components, and a symbol received by a symbol decoder is possibly decoded in an incorrect manner. <P>SOLUTION: Modification is made so that a time-averaged value of the DC offset in either or both of the I and the Q components is removed from the I and the Q components before symbol decoding. <P>COPYRIGHT: (C)2011,JPO&INPIT |
