METHOD OF TRANSMITTING PREAMBLE IN MULTIPLE ANTENNA SYSTEM

摘要

PURPOSE: A preamble transmission method using the other masking sequence in a multiple antenna system is provided to improve the reliability of the system and prevent the delay of a cell search or handover process. CONSTITUTION: A plurality of preambles is transmitted through a first transmission antenna(190-1). A plurality of preambles is transmitted through a second transmission antenna. A plurality of preambles is arranged to a crossed subcarrier. A plurality of preambles about the first transmission antenna and a plurality of preambles about a second transmission antenna have phases different from each other.
