METHOD AND APPARATUS OF GENERATING RANGING PREAMBLE CODE IN WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: A method and apparatus for generating a ranging preamble code without increase of detection complexity are provided to generate a ZC(Zadoff-Chu) sequence to a ranging preamble code about OFDMA(Orthogonal Frequency Division Multiple Access) symbols. CONSTITUTION: A cyclic shift is applied to each of a plurality of OFDMA symbols. A ZC sequence applying the cyclic shift is generated to the ranging preamble code. The cyclic shift is especially applied to each OFDMA symbol. The cyclic shift pitches with the predetermined equation.
