| Abstract: | The simulation models for composite fading channel, such as Rayleigh-Lognormal fading channel, Ricean-Lognormal fading channel and Nakagami-Lognormal fading channel, are presented based on Simulink?. These models can be applied to design SFN-based DRM systems and to analyze the performance of the designed systems. The probability density function, cumulative distribution function, average level crossing rate and average fade duration of each composite fading channel are analyzed, and some uniform expressions are derived. Simulation results validate the correctness of these expressions. |

| Keywords: | DRM SFN channel simulation probability density function average level crossing rate |
