- A downlink frame generation device arrange a plurality of synchronization channel symbols and a plurality of broad-casting channel symbols in a common bandwidth of a system so that the symbols may neighbor each other on the time axis. The downlink frame generation device applies a precoding vector to the synchronization channel symbols and the broadcasting channel symbols to generate a plurality of downlink frames corresponding to a plurality of antennas. The precoding vector is variable by a sector for transmitting a plurality of downlink frames and a subframe in which a plurality of synchronization channel symbols are positioned. The precoding vector is independent of an index of a subcarrier.
