Abstract
(EN)
There is provided a diversity receiving apparatus (1) that comprises: a receiving unit (4) for receiving a frequency-division multiplexing signal on which a carrier group is multiplexed; a first demodulating unit (5) for outputting a first data carrier and a first transmission control carrier; a second demodulating unit (6) for outputting a second data carrier and a second transmission control carrier; a timing adjusting unit (7) for synchronizing processing timing of the first demodulating unit (5) and the second demodulating unit (6); a first combining/selecting unit (60) for combining or selecting a first transmission control carrier and a second transmission control carrier; a second combining/selecting unit (8) for combining or selecting a first data carrier and a second data carrier; a decoding unit (13) for decoding a transmission control signal using the transmission control carrier selected by the first combining/selecting unit (60); and a detecting unit (14) for detecting frame synchronization.
