WIRELESS COMMUNICATION APPARATUS AND WIRELESS COMMUNICATION SYSTEM

摘要

According to an embodiment, a wireless communication unit includes a media access control (MAC) unit. The MAC unit includes a clock unit, an acquisition unit and a calculation unit. The clock unit includes a register which stores periodically counted-up first time information. The acquisition unit acquires a statistic for reception quality information on the received packet. The calculation unit normalizes the second time information, weights the normalized second time information using a time weight based on the statistic, and calculates a time correction value for correcting the first time information, using the weighted and normalized second time information. The time weight increases with increasing link stability indicated by the statistic.
