SMART KEY APPARATUS AND METHOD FOR PROCESSING SIGNAL OF SMART KEY APPARATUS

摘要

A smart key apparatus and a method of processing a signal from the smart key apparatus is provided and the smart key apparatus includes a plurality of antennas that receive a Low Frequency (LF) signal from a vehicle via a plurality of reception axes. In addition, an LF reception controller receives the LF signal via a reception antenna which is determined by sequentially verifying a reception level according to a set order of the plurality of antennas when receiving the LF signal and determines an antenna having a highest reception level as a reception antenna by comparing a reception level that corresponds to a plurality of antennas respectively. A signal processing unit processes the LF signal received via the reception antenna.
