A recursive algorithm for radio propagation model calibration based on CDMA forward pilot channel

Generic propagation model always have accuracy problems. Without model calibration, it can hardly be used in practice. This article develops a recursive algorithm on radio propagation model calibration for CDMA systems. An evaluation method is introduced and actual drive test results are used to verify the refined model´s goodness of fit. From the results it can be seen that the calibration method in this paper is feasible in practice.
