The radio resource management algorithms to be used in UMTS systems such as power control, frequency hopping and even time and spatial diversity cannot be independently considered in link and system level simulations. In this paper, a methodology to be followed when using time-series generated with a channel model is presented. Namely, a 3-state Markov model of the land mobile satellite channel is at large used to produce link level outputs for a full chip-rate DS-CDMA system, which are appropriate for system level simulations. Moreover, an insight on the practical advantages of using a semianalytical procedure for performance analysis (thoroughly validated by means of extensive Monte Carlo computer simulations) is presented
