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.

Description

technical field [0001] The present invention relates to a signal transmission / reception method used in a communication system based on an Orthogonal Frequency Division Multiplexing (OFDM) scheme, in particular, to a sequence generation method and a signal transmission / reception method using the sequence generation method, Wherein the sequence generating method enables the receiving end to effectively detect the sequence for a specific channel of the mobile communication system. Background technique [0002] The schemes of OFDM, OFDMA and SC-FDMA used in the present invention will be introduced in detail below. [0003] Recently, as the demand for high-speed data transmission increases rapidly, and the OFDM scheme has more advantages for such high-speed transmission, the OFDM scheme is used as a transmission scheme for various high-speed communication systems. [0004] The OFDM (Orthogonal Frequency Division Multiplexing: Orthogonal Frequency Division Multiplexing) scheme wi...
