ABSTRACT:
The invention provides an FFT-size detection method and system and a cell search method and system based on FFT-size detection, and more particularly to a cell search method based on FFT-size detection in cellular system. The cell search method utilizes two frames to correctly detect the actual cell ID. The cell search method uses the first frame to detect the actual FFT size of a received signal. When the FFT size is determined, the cell search method use the second frame to detect the cell ID of a base station outputting the received signal based on the FFT size.
