摘要： PROBLEM TO BE SOLVED: To actualize a receiving method which improves frame receiving performance by reducing missing of a frame and false detection.
SOLUTION: When a radio communication device 401 transmits a Data frame requiring an ACK frame, a destination station (radio communication device 402) is expected to transmit an ACK frame after the SIFS. Therefore, processing for detecting coincidence of a known pattern added to a top of a received frame is started from the time that the ACK frame is expected to be received, not adopting a usual method for detecting power change.
