A diversity reception apparatus having a simple configuration which includes only one AD conversion unit and receives analog modulated signals is provided. The diversity reception apparatus includes a switching unit that analog-multiplexes signals received by two antennas using time-division method and is placed in front of an AD conversion unit. The apparatus also includes a time-division separation unit that (i) obtains time-division multiplexed signals digitized by driving at the same frequency as driving frequency of the AD conversion unit and (ii) separates the time-divided signals into a signal per antenna. Moreover, the apparatus includes signal quality judgment units that judge each signal quality of the time-divided signals and a composition unit that executes composition processing based on the signal quality.
