PACKET MODE AUTO-DETECTION IN MULTI-MODE WIRELESS COMMUNICATION SYSTEM, SIGNAL FIELD TRANSMISSION FOR THE PACKET MODE AUTO-DETECTION, AND GAIN CONTROL BASED ON THE PACKET MODE

摘要

A method for automatically detecting a packet mode in a wireless communication system supporting a multiple transmission mode includes: acquiring at least one of data rate information, packet length information and channel bandwidth information from a transmitted frame; and determining the packet mode on the basis of the phase rotation check result of a symbol transmitted after a signal field signal and at least one of the data rate information, the packet length information and the channel bandwidth information acquired from the transmitted frame.
