Abstract  Abstract

A sequence generation method for allowing a reception end to effectively detect a sequence used for a specific channel of an OFDM communication system and a signal transmission/reception method using the same are disclosed. During the sequence generation an index is selected from among the index set having the conjugate symmetry property between indexes 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.
