To provide a diversity receiving apparatus and method in which all of an in-phase combining diversity method and a level comparing diversity method are applied.

The diversity receiving apparatus includes: a first signal adjusting unit 380 for amplifying a first signal received by a first antenna 220; a second signal adjusting unit 390 for amplifying a second signal received by a second antenna 210 and shifting the phase of the second signal; first and second mixers 310, 320 for respectively mixing output signals of the first and second signal adjusting units 380, 390 with an intermediate frequency; a signal combiner 340 for combining or selecting signals outputted from the first and second mixers 310, 320 and outputting the resulting signal to a demodulator 45; a phase detector 280 for extracting phase information of the signals outputted from the first and second signal adjusting units 380, 390; and a controller 360 for controlling the signal combiner 340 on the basis of the extracted phase information.
