<p>PURPOSE:To prevent divergence of an equalizer coefficient by releasing the control of revision of the equalizer coefficient at a prescribed time after the abnormal amplitude of a reception signal is not detected to control the equalizer coefficient revision processing. CONSTITUTION:An equalizer coefficient revision control section is limited from a time of the presence of an abnormal amplitude is detected in a reception signal and an equalizer coefficient revision calculation section 3 makes calculation. The limit of the revision of the equalizer coefficient is released at a prescribed time after the abnormal amplitude is not detected. Then the divergence of the equalizer coefficient is prevented by controlling the equalizer coefficient revision processing.</p> |
