<p>A selective diversity apparatus in which a pre-detection diversity system is used and branches can be switched without generating a signal error, etc., even at the time the reception of a communication physical slot having a short preamble signal zone, and a control method thereof. When a control physical slot is received in which a preamble signal zone contained in a burst received is sufficiently longer than the time necessary for selecting and switching the branches, judgment and switching of the branches are executed in the preamble signal zone, and when a communication physical slot not having a sufficient time is received, judgement of the branches is made during reception of the burst and switching of the branches is made in a guard time immediately before the burst after one frame. <IMAGE></p> |
