Channel tracking has not been considered by the WLAN standards named above‚ although it is well known that time-variant indoor radio channels can change their characteristics within one PHY burst. This paper presents some techniques for decision directed channel tracking‚ applicable in wireless OFDM systems.

The final version of the standard has recently appeared [3]‚ and provides detailed medium access control (MAC) and physical layer (PHY) specification for WLAN’s. In the 802.11 protocol‚ the fundamental mechanism to access the medium is called distributed coordination function (DCF). This is a random access scheme‚ based on the carrier sense multiple access with collision avoidance
