The study of wavelet transform on harmonic interference of the power system;

This paper introduces the effect of conduction interference,radiation interference and harmonic interference for electronic ballast inverter.

Based on the signal characteristic of Roran C and the composition structure of the receiver,this paper analyzes the capability that the receiver restrains the narrowband carrier wave jamming,and presents the corresponding mathematic model.

Inevitably, some technically difficult problem must be solved, including the variety of speed about tropospheric propagation, the sky wave disturbance and the near-far problem.
