Abstract
A frequency tuning apparatus includes: a frequency tuner configured to tune an oscillation frequency of an oscillator based on target information extracted from a mapping table in correspondence to a target frequency, and oscillation information collected from the oscillator; and a frequency compensator configured to compensate for a compensation error between the tuned oscillation frequency and the target frequency based on an offset table.
Claims24
A frequency tuning apparatus comprising:
- a frequency tuner configured to tune an oscillation frequency of an oscillator based on target information extracted from a mapping table in correspondence to a target frequency, and oscillation information collected from the oscillator;
- a frequency compensator configured to compensate for a compensation error between the tuned oscillation frequency and the target frequency based on an offset table;
- and
- a controller configured to activate the frequency tuner before receiving a data packet, and to inactivate at least a portion of the frequency tuner during receiving the data packet.
