A simplified relativistic configuration interaction method is used
to study the dielectronic satellite transition processes.
In this method, the infinite resonant doubly excited states can be
calculated, and furthermore, the whole high-n dielectronic satellite transition
processes can be treated conveniently by interpolation (rather than extrapolation)
in the frame of Quantum Defect Theory. As an example,
we calculate the contributions from high-n dielectronic satellites to
the 
resonance line in helium-like iron, and the results
are in good agreement with the experimental measurements.
