Conversion of reference tapped delay line channel models to discrete time channel models [UMTS]

When simulating reference tapped delay line channel models, there is usually the problem of matching all the replica delays with simulation sampling instants. To avoid a substantial increase in simulation time, several conversion methods for obtaining channel models, with all replica delays matching sampling instants, are studied. Simulation results of a WCDMA system using RAKE receivers are shown for verifying the closeness of the results of the channel models.
