Study on propagation model tuning based on TD-SCDMA System

This paper provides a fast and precise tuning method based on linear least-square theory to tune the standard general macro cell propagation model. This method depends on existed tuning methods and the CW (Continuous Wave) testing data of a certain city. Furthermore, using this method can obtain actual outdoor propagation model fitting for TD-SCDMA network. Simulation results indicate that the calculating complexity is reduced obviously, and the maximum error of forecasting data calculated by tuned model reduces by 20.7%, and the tuned model matches the local ratio propagation environment much better.
