ABSTRACT:
An in-phase combining diversity receiving apparatus is disclosed by which the size (gain) of a receiving signal as well as its phase is controlled and signals received through each antenna pass through different paths so that an imbalance of receiving signal power is solved. The diversity receiving apparatus includes a first signal adjusting unit for amplifying a first signal received by a first antenna and for phase-shifting, a second signal adjusting unit for amplifying a second signal received by the second antenna and for phase-shifting, and a controller. The controller operates as to measure powers of an original receiving signal, the first signal and the second signal, and controls the first and second signal adjusting units.
