Abstract

Disclosed are sequence generation methods for allowing a reception end to effectively detect a sequence used for a specific channel of an OFDM communication system, and signal transmission/reception methods using the same. One of the methods relates to an index selecting from among the index set having the conjugate symmetry property between indexes during the sequence generation, and a specific part corresponding to the frequency '0' is omitted from a transmitted signal. In addition, a reception end can calculate a cross- correlation value between a received Rx signal and each sequence using only one cross-correlation calculation based on the conjugate symmetry property.
