Abstract

Two types of scrambling code planning methods for multi-layer asynchronous 3GPP W-CDMA systems are developed by modifying the PN offset planning methods for synchronous CDMA systems. One is based on the reuse of code sets and the other is based on the graph coloring optimization. A condition that guarantees no code set confusion is derived. Design examples demonstrate that the graph coloring based method can be more efficient than the reuse-based method, and applicable to a wide variety of real W-CDMA networks
