Simulation of Digital Radio Mondiale channel model

This paper analyzes the channel model of Digital Radio Mondiale and discusses the parameters given by the specification. Watterson model is used to simulate the radio channel. We describe the implementation of Watterson channel model in details, including the channel multi-path and timing-variability. Multi-level interpolator is used in our realization scheme to improve calculation efficiency. The simulation results are given and indicate that the timing and frequency selective fading effect of the DRM channel are well modeled.
