摘要： A downlink frame generation device arrange a plurality of synchronization channel symbols and a plurality of broadcasting channel symbols in a common bandwidth of a system so that the symbols may neighbor each other on the time axis. The downlink frame generation device applies a precoding vector to the synchronization channel symbols and the broadcasting channel symbols to generate a plurality of downlink frames corresponding to a plurality of antennas. The precoding vector is variable by a sector for transmitting a plurality of downlink frames and a subframe in which a plurality of synchronization channel symbols are positioned. The precoding vector is independent of an index of a subcarrier.

摘要： Provided are a cell search method in an Orthogonal Frequency-Division Multiplexing (OFDM) cellular system, a frame transmission method thereof, and a forward link frame structure thereof, which are capable of reducing the amount of time and computational complexity that are required for a cell search. In the cell search method, a terminal searches for a target cell by using reception signals received from a plurality of base stations each transmitting a frame of its cell. The frame of each of the cells includes M sync channel symbols obtained by frequency-division multiplexing a primary sync channel code sequence, which is common in all the cells, and each secondary sync channel code sequence according to a hopping pattern of each of the cells, where the hopping pattern contains M secondary sync channel code sequences and has one-to-one correspondence to a code group to which scrambling code of the cell belongs, and M is a natural number equal to or greater than 2. An arbitrary hopping pattern used in the OFDM cellular system differs from the result of cyclically shifting the hopping pattern, other hopping patterns, or results of cyclically shifting the other hopping patterns. The method includes obtaining symbol synchronization for the reception signals by using a matched filter, detecting a hopping pattern of the target cell based on the obtained symbol synchronization, and detecting a code group of the target cell based on the detected hopping pattern.
