Abstract
An RF unit receives predetermined signals. The RF unit amplifies the received signals. A gain control unit controls the gain at the RF unit based on the amplified signal and has the RF unit use the controlled gain. The gain control unit performs different controls on the received signals, depending on the case when the received signal is a known signal placed in the beginning of packet signal and the case when the received signal is a signal other than the packet signal.
Claims3
1-14. (canceled)
A receiving apparatus comprising:
- a receiving unit configured to receive a signal;
- an amplifier configured to amplify the signal received by the receiving unit;
- and
- a control unit configured to control a variable gain in the amplifier based on a signal amplified by the amplifier and configured to have the amplifier use the controlled gain, the control unit including:
- an averaging unit configured to average the magnitude of signals amplified by the amplifier;
- and
- a decision unit configured to determine the gain such that the magnitude averaged by the averaging unit is brought close to a target value when the receiving unit receives a signal,
- wherein the decision unit changes the magnitude of the target value, depending on the case when the signal received by the receiving unit is a known signal placed in the beginning of packet signal or the case when the signal received by the receiving unit is a signal other than the packet signal.
