CELL SEARCH METHOD, FORWARD LINK FRAME TRANSMISSIN METHOD, APPARATUS USING THE SAME AND FORWARD LINK FRAME STRUCTURE

摘要

Provided are a cell search method, a forward link frame transmission method, an apparatus using the methods, and a forward link frame structure in an Orthogonal Frequency Division Multiplexing cellular system, wherein the time it takes to perform a cell search and the complexity of the cell search can be reduced. The cell search apparatus includes a sync acquirer which receives a signal according to a forward link frame comprising a plurality of sync channel symbols each having different intervals between the adjacent sync channel symbols and achieves synchronization of the sync channel symbols using a sync channel of the received signal, and a boundary detector which detects a frame boundary using an interval pattern between the sync channel symbols, based on the achieved synchronization.
