DC offset correction device and its method |
摘要 |
A reference signal and a feedback signal are written to memory and the state of a power value of a reference signal is used for judging whether the current signal is in a normal state, burst state, non-modulation state or no-wave transmission state. If the state is judged to be the burst state or no-wave transmission state, a DC offset correction is performed by selecting a feedback signal type DC offset correction method in which a DC offset is corrected by using only a feedback signal. If the state is judged to be the normal state or non-modulation state, a DC offset correction is performed by selecting a reference signal type DC offset correction method in which a DC offset is corrected by using a differential signal between the reference signal and feedback signal.
