Abstract
The present invention provides a method and apparatus for transmitting a preamble for multiple channel estimation. The method includes generating a channel estimation sequence, allocating the channel estimation sequence to some of a plurality of symbols in which a preamble is transmitted, and transmitting the preamble. The channel estimation sequence is generated by bisecting a sequence having a length N, generating a first sequence and a second sequence by adding a Zero-padded Suffix (ZS) having a zero value to a last part of each of the two bisected sequences, copying the first sequence and the second sequence at least once, and allocating the first sequences and the second sequences to some of the symbols.
