This paper presents a new simulation methodology
to study the effect of radiated transient disturbances on digital
communication systems. The procedure is divided in two stages.
In the first one, FDTD numerical simulation is used to determine
the transient levels coupled to the antennas. In the second stage,
these levels are analyzed by means of a signal processing
simulation software to determine the degradation caused in the
system. The procedure is applied to a DAB system in car when a
radiated interference is generated by a transient in a vehicle
cable. The results show that the amplitude of the radiated
transient coupled signal is a key parameter, but it is also essential
to take into account other parameters such as burst duration and
