Abstract
Provided are a method and apparatus for generating a preamble of a data packet. The method includes operations of generating a first field, a second field, and a third field; generating a synchronization sequence for synchronization between a data packet transmitter and a data packet receiver, generating a channel estimation sequence (CES) for estimation of a property of a channel in which the data packet is transmitted, and generating an additional sequence indicating an end position of the synchronization sequence in the preamble, and an additional sequence indicating information about a structure of the CES; and respectively recording the synchronization sequence, the additional sequences, and the CES in the first field, the second field, and the third field, thereby generating the preamble.
