Patent ID: 7304965

Claim:
A method, for use in a transmitter in a mobile communication system, the mobile communication system having multiple code groups having inherent code indices in response to each of slots, selecting one code group from among the multiple code groups, and generating a second synchronization code corresponding to any one slot from among multiple slots, which are included in the selected code group, the method being performed to determine position information designating a Hadamard code necessary for generating the second synchronization code, the method comprising the steps of: (1) in response to any one slot, outputting a value, which is obtained by subtracting 1 from a code index included in the selected code group, as a binary bit row; and (2) selecting one bit row, which employs the binary bit row as an upper bit and employs a binary code “0000” as a lower bit, as position information which designates the Hadamard code.
