Abstract (en)
[origin: WO0003549A2] Disclosed is a communication device for a base station in an asynchronous CDMA communication system. A common short code generator generates a common short code used in common by multiple base stations, a pattern generator generates a unique modulation pattern, and a long spreading code generator generates a unique long spreading code at predetermined periods. A specific channel transmitter spreads a transmission signal on a specific common channel with the long spreading code. A common short code inserter modulates the common short code with the modulation pattern, punctures the transmission signal on the common channel at predetermined periods and inserts the modulated short common code in the punctured transmission signal.
