ABSTRACT:
In a spread spectrum communication system, as base station transmission channels are used a synchronizing channel for continuously transmitting a predetermined PN code from a base station (generated by a synchronizing pilot channel generating block), a identifying channel for continuously transmitting a predetermined multivalued PN code every base station (generated by an identifying pilot channel generating block), and a communication channel for enabling the identification of a base station transmitting data by multiplying the multivalued PN code used in the identifying channel by communication data after spectrum spreading (generated by a communication channel generating block).
