To realize power saving of a receiver apparatus for receiving time-division multiplexed signals. In the receiver apparatus, power is supplied to a receiver circuit in accordance with an operation start time. A signal is received through the receiver circuit, and a quality of the received signal is evaluated by a signal quality evaluation unit 109. Control is exercised to set a late operation start time if the quality of the received signal is good, and an early operation start time if the quality of the received signal is bad. In this way, a period for supplying power to the receiver circuit can be adjusted according to the quality of the received signal. This makes it unnecessary to fix, as in conventional techniques, a long power supply period in consideration of the case where the signal quality is bad. As a result, more power saving can be achieved. |
