PROBLEM TO BE SOLVED: To provide a reception device having a smaller bit error rate to the reception signal of a wide dynamic range. SOLUTION: Signals which are gain-controlled by a first gain control circuit 2 are orthogonally detected by orthogonal detectors 3 and 4 and an I signal and a Q signal are outputted. A second gain control circuit 5 controls the gain of the I signal. A third gain control circuit 6 controls the gain of the Q signal. The I signal and/or the Q signal as control signals to a first gain control circuit 2, the I signal as the control signal to a second gain control circuit 5 and the Q signal as the control signal to a third gain control circuit 6 are obtained from a digital demodulation part 11 and supplied to the control circuits, respectively. |
