A radio receiver includes a branching unit, a first gain-control system, a second-gain control system, and a signal processing unit. The branching unit branches a radio signal received by the radio receiver into two signals. The first-gain control system performs a gain control of a pilot signal in one of branched signals, and the second gain control system performs a gain control of a data signal in another of the branched signals. The signal processing unit synchronizes frames in the received radio signal. The signal processing unit outputs a gain signal to each of the first gain-control system and the second gain-control system. The first gain-control system and the second gain-control system perform the gain controls based on the gain signal.
