Abstract: A method for generating a downlink frame and a cell search method are provided to improve the cell search performance by making a short sequence into a scrambling sequence. A sequence generation part produces a plurality of short sequences and a plurality of scrambling sequence for reducing the neighboring cell interference, and then transmits the generated scrambling sequence to a synchronous signal generator(S510). The synchronous signal generator produces the secondary synchronous signal by using the short sequences and scrambling sequence received from the sequence generation part(S520). A frequency mapping part maps the secondary synchronous signal and transmission traffic data to the time and frequency domains to generate the frame of a downlink signal(S530). An OFDM transmission unit receives the frame of the downlink signal, and then transmits the frame through a transmission antenna(S540).
