Abstract: PURPOSE: A method for obtaining codes of base stations is provided to insert a cyclic code into a transmission frame to transmit pilot/traffic channel signals, so as to reduce a time spent on a frame synchronization and a group code obtained in an asynchronous transfer mode(ATM) code division multi access(CDMA) system. CONSTITUTION: A terminal detects a symbol timing of cyclic codes through an interfacing filter for channel identifying codes. The terminal tests a max outputting point of the interfacing filter to detect a long-cycle code timing. The terminal loads a group code into a group identifying code circuit, to upgrade the group code. The terminal firstly correlates a received I pilot code with a generated group code. The terminal compares a threshold with the firstly correlated outputs, to decide whether cell codes are synchronized. The terminal respectively loads cell codes included in the group code into a cell identifying code circuit, to generate the cell codes. The terminal secondly correlates self-generated group/cell codes with received I/Q pilot codes. The terminal compares the threshold with the secondly correlated outputs and decides whether the cell codes are synchronized. If the cell codes are not synchronized, the terminal repeats the processes from the beginning.
