A novel call admission control (CAC) scheme using fuzzy interference for a wideband code division multiple access (CDMA) cellular system is proposed. The fuzzy CAC first estimates the newly arriving mobile station's (MS) effective bandwidth and its mobility information, and then makes a decision to accept or reject the MS's connection request based on the estimates and the system status. Numerical results are given to demonstrate the performance of the proposed fuzzy CAC scheme in terms of new call blocking probability, handoff call dropping probability, outage probability and resource utilization.
