Abstract
A diversity receiving apparatus for receiving data that has been primarily modulated and then secondarily modulated includes a plurality of uni-directivity antennas arranged so that they orient in different directions, a signal information detector for detecting signal information of all frequency bands of received signals of each of the uni-directivity antennas, a branch selector for selecting one of received signals of the individual branches received by the uni-directivity antennas, a secondarily modulated data demodulator for demodulating data that has been secondarily modulated as the received signal selected by the branch selector, and a primarily modulated data demodulator for primarily demodulating data that has been primarily modulated as an output signal of the secondarily modulated data demodulator, wherein the branch selector is controlled corresponding to an output signal of the signal information detector.
