摘要

Disclosed is a communication apparatus including: an estimating unit which estimates a first wireless channel state from a first frame wirelessly received and a second wireless channel state from a second frame wirelessly received after the first frame; a storing unit capable of storing the first wireless channel state as a past wireless channel state; a comparing unit which compares a difference between the second wireless channel state and the past wireless channel state with a threshold value; and a processing unit which discards the second frame when the difference is larger than the threshold value.
