摘要：
A method for generating a downlink signal and searching for a cell from the downlink signal in an OFDM-based cellular system is provided. Thus, a pilot pattern is formed in the downlink signal, and the pilot pattern is formed of a product of a cell-specific scrambling code and a cell group-specific code. The scrambling code is different for each cell and the same for each sub-frame, and the cell group-specific code is different for each cell and different for each sub-frame.
