Patent ID: 7289483

Claim:
A signal transmitting apparatus for cell search in a mobile communication system, comprising: a primary synchronization channel (P-SCH) transmitter for placing a first synchronization code at the start of each of a plurality of slots which forms one P-SCH frame to provide slot synchronization and for transmitting the P-SCH; and a secondary synchronization channel (S-SCH) transmitter for transmitting a base station group specific code at the start of each slot in an S-SCH frame and a base station specific code following the base station group specific code in at least one slot, the base station group specific code representing one of the base station groups and the base station specific code representing one of the base stations in the base station group, wherein correlation and detection operations of the cell search are performed in two steps and without searching a broadcast channel (BCH) for the base station specific code, and wherein a same synchronization code is inserted into each slot of a frame to transmit the base station specific code.
