ABSTRACT:
A control unit, in cooperation with an interface (IF) unit, a modulation unit and a baseband processing unit, produces a packet signal composed of a plurality of streams. While using as a reference a first known signal assigned to one of the plurality of streams and performing a cyclic timing shift within the first known signal on a first known signal assigned to another stream, the control unit performs a timing shift also on an extensional known signal assigned to a stream where no data is assigned. The amounts of timing shift are given degrees of priority beforehand and for the stream where data signals are assigned the control unit uses the amounts of timing shift in descending degree of priority. For the stream where no data signal is assigned, the control unit uses the amounts of timing shift also in descending degree of priority.
