- Abstract
- An apparatus of transmitting a long training field includes: a station number determination unit configured to determine at least one station to be transmitted using transmission data or channel status information; a transmission stream allocation unit configured to determine the number of transmission streams for each of the least one station determined by the station number determination unit; a long training field number calculation unit configured to calculate the number of long training fields required for each of the at least one station determined by the transmission stream allocation unit and determines the least common multiple of the number of calculated long training fields of each station; and a long training field allocation unit configured to allocate the long training fields for each station to subcarriers allocated to each station to correspond to the least common multiple of the determined long training fields.
