摘      要：正The load will change drastically when a new user accesses the CDMA *** the advanced outer loop power control（OLPC） technology will be taken to enrich the target signal interference ratio （SIR） and improve the system *** author introduces the ever existed problems about WCDMA outer loop power control for multiservice and analyzes the power control theoretical *** system simulation the author explains how to obtain the theoretical performance and parameter optimization of power control algorithm. The OLPC algorithm is improved and the performance comparisons between the old algorithm and the improved algorithm are given. The results show the good performance of the improved OLPC algorithm and prove the validity of improved method for multi-service.
