摘要 |
Reception timing of a signal consisting of a valid symbol section and a guard interval section is controlled properly. According to a result of auto-correlation calculation performed by a guard correlation processor, a timing adjustment block generates a control voltage for adjusting the reception timing of the valid symbol section. A first and a second loop filter filter the control voltage signal generated by the timing adjustment block and sends it to a switch. An inter-symbol interference decision block decides whether an inter-symbol interference is generated according to the result of the auto-correlation calculation performed by the guard correlation processor, and controls the switch according to the decision result. Where, in the first loop filter, a comparatively large gain is set while in the second loop filter, a comparatively small gain is set.
