Abstract
Preamble transmission in a broadband wireless communication system is provided. A method for transmitting a preamble includes determining a sequence as the preamble according to a transmit bandwidth, allocating sub-blocks of the sequence to a plurality of transmit antennas used to transmit the preamble, the number of the sub-blocks allocated to each antenna falling within two consecutive integers, and transmitting the preamble through the plurality of the transmit antennas according to the allocation result of the sub-blocks.
