<P>PROBLEM TO BE SOLVED: To restrain reception accuracy from deteriorating when a known signal for transmission line estimation is transmitted. <P>SOLUTION: A control unit 30 generates a packet signal formed by a plurality of series while cooperating with, an IF unit 26, a modulation/demodulation unit 24 and a baseband processing unit 22. The control unit 30, while performing a cyclical timing shift within a known signal on a known signal disposed in other series referenced to a known signal disposed in one of the series where data signals are disposed, also performs timing shift on an additional known signal disposed in a series where no data signals are disposed. The control unit 30 has the timing shift amounts prioritized in advance, so that the control unit 30 uses timing shift amounts for series where data signals are disposed in decreasing order of priority of timing shift amounts, and also uses timing shift amounts for series where data signals are not disposed in decreasing order of priority of timing shift amounts. <P>COPYRIGHT: (C)2012,JPO&INPIT |
