摘要:	In a WCDMA Node-B, orthogonal variable spreading factor (OVSF) codes are both valuable and limited. Many efforts are being made to create OVSF code-assignment schemes that support a maximum number of users. Here the author (a) proposes a batch arrival and partial loss queuing model to evaluate OVSF single-code assignment system performance, and (b) derives expressions for calculating two important system performance measures (partial loss probability and bandwidth utilization) that respectively denote subscriber service quality and operator profit. Results from a simulation test suggest that the proposed model has utility in the construction of WCDMA networks.
